Object variable or with block variable not set in 2 places but nowhere else with same code

In only 2 of 27 buttons this error occurs. In the first instance, it works, but any other selection after causes error.

When selecting Test 28 (or 29) with train 7 (The first Train) They work just fine.
Any train after causes the error on 28 and 29.
Train number is a value carried through multiple forms in a text box.

The issue highlights "frmTest29.txtTrain = Me.txtTrain"
The value of "Me.txtTrain" is correct (7, 8, 9, etc.)
The value of "frmTest28.txtTrain" contains the error.

If anyone can shine some light on this issue it would be greatly appreciated.

For me, it raises that error here:

    Else
        UserForm21.Label3.BackColor = vbWhite
    End If

You don't have a userform21.

Your file is far too difficult to troubleshoot. When it errors and I have to stop code, I have to attempt to open the file again two times, closing any blank workbooks that open, just to get back to the login screen and start over. After spending about 2 hours trying to figure out what's going on I think I must bow out if I haven't already found the problem.

OK, was finally able to raise the error. Will take some time to investigate.

Thank you so much for all of your help.

After almost giving up, I went back to fix this issue and that fixed the error. Changing UserForm21 to frmTest29 solved the issue.
Thank you for you help and patience.
