It seems like you should do this:
• from the menu, select Manage > Database
• find the field for the invoice number
• double-click it (or select it and click Options)
• select 'Auto-enter options'
• the option 'Serial number' should be checked and display 9 as the next number. Change this value to 5.
Thanks, I'll try and let you know, again thanks for your interest of helping me!
If consecutive numbers are important, you might, in the future, void invoices instead of deleting them. Then there will be no gaps in your sequence.
It worked! I'm so happy! You know a lot! Regards from Mexico!
It's a good idea, I'll do that, thanks a lot for your input !
