Hi! I hv defined $sourcename; i do hv the required permissions properly set up. The source file is taken from the command line argument. I guess if it doesn't point to correct file, the error would be something different. This program used to work earlier and now it gives this error for any excel file gievn as input. The complete error message i get whenever i tried to run this program is : "Could not open source Excel file myglus.xls: at Excel.pl line 21."
