I have bought the Sximo Builder and I have downloaded and installed the Invoice Generator module. I am not a coder but I am passionate about IT. Your software looks impressive. Keep it up !

1) When you change the Qty for example and type Enter, it gives an error but does the calculation. Tab works well.

2) When Print Invoice is clicked, the following error:

"FatalErrorException in SinvoiceController.php line 174:
Class 'PDF' not found"
is displayed.

Also, if that can help, I can provide corrections to some English errors.

Best regards
Robert
