Problem to line

"Continue For" is not really a proper syntax, if it's a comment, try:

If (Trim(ConfigWS.Cells(i, "D").Value) = "") Then //Continue For

Select allOpen in new window

or

If (Trim(ConfigWS.Cells(i, "D").Value) = "") Then
     //Continue For
    
End if

Select allOpen in new window

Looks good but

1/ Is the value "i" declared and an integer or long type
2/ Has ConfigWS been created as a worksheet object

What exact error are you getting?

A single line of code often does not give us the information to correctly analyse the issue and so posting the workbook or at least posting the entire function will help us in resolving the issue

I want to skip the loop, within If. What to adjust?

Yeah, "Continue For" isn't proper syntax.

Instead of looking to continue, look for something to not continue and perform your action....

For i = 1 To 100
    If Trim(ConfigWS.Cells(i, "D").Value) <> "" Then
        'Do your thing
    End If
End if

Select allOpen in new window

Continue For is part of Visual Studio 2015.

If this is VBA, then you will need to do what I describe in this Next Iteration article:

// is not a valid comment indicator in VBA

>>// is not a valid comment indicator in VBA
exactly Aikimark... thks for highlighting, was posted too quickly and still thinking to code in C# environment...

we should use ' instead for commenting in VBA.

exit is not the same as continue. Do you want to stop the loop (and continue with execution after the loop) or skip this loop iteration (and continue with the next loop value)?
