HI, Can someone help please.

I am trying to import inventory items that we have fixed with correct pricing, categories etc.
I have imported around 10 different sections of the inventory, however one is refusing to import and i keep getting a message for certain line items " supplier code does not exist and group code does not exist.

I have cut and pasted onto the sections that did work and they are still not importing.

Has anyone got any ideas before the consign everything to the trash.

Thanks

Shaun
