Must close or hide topmost modal form first

[realniceguy5000]

Hi,
I'm having problems with a couple userforms that I have included in the attached workbook. Could someone take a look and advise what is going wrong.

I placed some stops in and step through and it seems to work fine, however when I run the code I get an runtime error.

"Must close or hide topmost modal form first"

Please Advise:

Thank You, Mike

I think I may have helped. Let me know

Thanks Mordred... Still getting the same error after I scan the upc. It looks like when the lot number userform comes up is when the error shows up. But not sure just yet. It's hard to tell because it works when I step through the script?

Any other thoughts?

Thank You, Mike

Still cant get this working, I have redone the workbook to include only one user-form and although I don't get the error any longer it skips through all the code most of the time. This must be related to time.

Does anyone have any suggestions?

Here is a copy of what I am working with now.

Thank You, Mike
