Field validation

[Waldemar]

Trying to set up the barcode generator (Little Appy Co) suggested by airtable - however the content field is not valid. 
I have tried all the suggested field types numbers / auto number / single line text etc but still telling me when I try to generate invalid field. 
Does anyone know what I am doing wrong.

Hmm, the screenshot indicates the 'Barcode' field is the problem, and that needs to be an attachment field.  What field type is the 'Create Barcode' field right now?

Hi @TheTimeSavingCo : I managed to resolve : I just hadn't set up field correctly - I did just post an Automation issue that I am having real issues with. I'm only just learning but been trying to resolve this for a day and a half. If you have any insight would be great > https://community.airtable.com/t5/automations/automation-add-to-inventory/td-p/193193
