Sorry... But I have always the same problem...

The error is: Impossible locate MyExcelSheet.xla!MySub

MyExcelSheet.xla is located in C:\Documents and
Settings\UserName\DatiApplicazioni\Microsoft\AddIn s and it contains codes
for adding a custom button to Excel application. After setting OnAction
property with a value < "ThisWorkbook.FullName" & MySub as suggested me
from the good Bernie, the error appears!!

Someone help me???

Sorry for my english but I'm very hopeless....
