VB Macro from Excel in Crystal Reports for Barcode 128

[bojimuncher]

Hello,

I am trying to use the following VB macro that works in Excel to encode Barcodes using barcode 128 in Crystal Reports. (Cant use 3 of 9 because I need a space and a comma) Can anybody help me get this to work in Crystal or have a different method of getting Barcode 128 to work in Crystal Reports? I've done a bit of Googling and the answer always ends up with a "Buy our product."

Edit: Crystal Reports 11

Thanks,
