How To Fix "Runtime Error 424 ‘Object Required’" – VBA (Excel)

If you are utilizing Excel, it’s possible you’ll encounter the “Runtime Error 424” error with message “Object Required”.

This is an error with VBA (Visual Basic for Applications), and principally exhibits whenever you’re referencing an object which both does not exist or is exterior the present scope.

If you are seeing the error as somebody “developing” any macro / automated performance in an excel spreadsheet, the probably drawback is that you simply’re calling an object “out of context”. This implies that you could have loaded an object, however its contents may have been modified or changed. There are additionally a number of different potential points, fixes for which I’ll clarify on this tutorial…

Cause

The error you may see could have the next message:

Run-time error ‘424’

Object required

To clarify why the error exhibits, and what it means – Microsoft famously launched its “Visual Basic” package deal within the late 90’s.

This supplied fundamental capabilities with the system, permitting pastime builders to create easy purposes. VB was an enormous hit.

Because of this, Microsoft launched “VBA” (Visual Basic for Applications) of their Office suite of software program, particularly Excel and Word. This allowed developer-varieties to create automated performance in Excel spreadsheets, referencing “objects” within the sheet itself and so forth.

Each time you employ Visual Basic, what you are doing is invoking a collection of “objects” into reminiscence. These objects are merely variables with a collection of additional performance utilized, together with customized capabilities and so forth. The drawback – and this extends via most programming languages – is that when you’re referencing an object which has not been invoked, the applying will fail.

Solution

If you wish to repair the issue it is advisable to first guarantee the information is current within the system, after which that you simply’re in a position to reference it accurately. This tutorial will clarify how:

1. Ensure You Have Defined Variables Correctly

The major subject is that you have known as a way on a variable (object) which does not exist. The commonest motive for that is that you have merely misspelled the variable’s identify, and have thus not declared it in your VBA software. Take the next instance:

Sub Test()

Application33.WorksheetFunction.Sum (Range(“A1:A100”))

End Sub

The above will elevate the error since you’re making an attempt to name the WorksheetFunction technique on an object referenced at “Application33”.

Unfortunately, the Application33 object does not exist in reminiscence, stopping your software from having the ability to load it. To repair this, it is advisable to undergo your supply code (the inaccurate reference will virtually all the time be referenced) and proper any misspelled object names.

2. If Using Excel, Ensure Ranges / Selectors Exist

One of the commonest causes for the error is that you simply’re making an attempt to reference an object or worth that does not exist. This is a typical subject with the likes of utilizing VLookup or one of many ActiveX objects. If you expertise this error, it is advisable to make sure the code is referencing solely objects which exist:

Private Sub Test()

This will elevate an error

Application.WorksheetFunction.VLookup(TeamName, Range(“TeamNameLookup”), 3, False).Value

The worth must be

Application.WorksheetFunction.VLookup(TeamName, Sheets(“YourSheetName”).Range(“TeamNameLookup”), 3, False)

End Sub

The above implies that you are making an attempt to name the assorted worksheets, and their respective “Range” / “Value” capabilities with out the sheets being discovered or declared. To repair this, it is advisable to make sure you’re calling “Range” or “Value” on the respectively scoped objects.

3. Ensure You Have The Correct Definitions

Finally, one of many extra frequent causes for the error is that you simply’re not defining your variables accurately.

From incorrectly defining variables as improper object definitions, to calling “Option Explicit”, it could be the case that you simply’re making an attempt to reference variables / objects which aren’t outlined just because they have not been outlined correctly.

For instance…

Option Explicit

Private Sub Test()

Here it is advisable to explicitly declare the variables earlier than making an attempt to reference / populate them

For instance…

Dim your_path As String

Set your_path = “x/y/z”

End Sub

In the instance above, if the “your_path” variable will not be declared earlier than making an attempt to set it, you’ll find yourself with the 424 error (because the “your_path” object does not exist). From right here, you additionally want to make sure you’re in a position to name the related objects (when you’re referencing a worksheet worth, it is advisable to make sure the worksheet exists and might be loaded).

Obviously, there are a selection of different cases of this error. Because of the precise nature of everybody’s code being completely different, I can’t undergo each single potentiality. Hopefully you may see that the error is brought on by an invalid variable reference in your system.
