Hi,
I am exporting data from a module into excel workbook.  THis works fine... until...I export the same data 10 minutes later and I get duplicates in my sheet.  There is code to "delete" the previous sheet but it is giving errors.
The DELETION of records is not working.
See two images.  One of them shows the code and the other shows the error.
"Internal server error" worksheet.rows.delete Error :3866
QUESTION: Why am I getting this error?
