Row[0] is my header row and has fixed cells.

I do have more than one column, but I figured get one column working and 
adding the others will be the same.  I do see a math error, though - I 
set the number of row to the number of records in the file, but I forgot 
to add in the header row, stgInvOps.RowCount needs to be one greater 
than the number of records.

That aside, I'm still having trouble getting the system to read from the 
file, and with the math error should get an out of range error not 
access denied or SIGSEGV.   In fact, I replaced 'rowNum <= 
stgInvOps.count' with 'not eof(inventory)', and got the same error.

Thank you for your help thus far.
