On Error, Restart Function

You could use the GoTo command .... or .... you could simply recalll the Function.

Something like :

Option Explicit

Sub ErrorTest()
OnError:      ErrorCommand

'All of your macro code here ....

ErrorCommand:

    ErrorTest
    
End Sub

You can clear the error first, then call the function. However, this is an unusual thing to do. I'm following to see how you make out.

Methods

With Err Object there are two methods that you can also use.

• Err.Clear: This method clears the error number and error description from VBA’s memory (It’s different from “On Error GoTo -1” as it doesn’t completely reset the error).

Option Explicit

Sub ErrorTest()
OnError:      ErrorCommand

'All of your macro code here ....

ErrorCommand:
    Err.Clear
    ErrorTest
    
End Sub

Out the error handler within the Function.
