I have been working on creating an excell add-in. During the first
week or so, I tested the add-in by "adding it" through the ToolsAdd-
ins process. It worked fine then. But since then I have been
building the code in it and just today when I tried to access it using
the ToolsAdd-ins process, I get the error that it is not a valid add-
in. Does anybody have some ideas on what I could have done to make it
not a valid add-in? Are there size limitations, exclusions of certain
subroutines or library references, etc?

I have made some 'empty' add ins just to test, and they loaded fine.

Thanks in advance for any help

Is the extension still .xla?

If it is then open the add-in as a normal workbook, so not via Tools,
Add-ins,
then go to the VBE, Select the ThisWorkbook module of that add-in and do
View, Properties and make sure IsAddin is True.
If it is not then change and safe.
