Attachment formula

Hello-

Is there a formula out there that if a cell is not blank or a specific option from a drop down is selected, a attachment is auto populated? Basically I need a static LOGO for my Interface Designer and right now the logo is dragged or added manually with each record in order for it to show at the top of my header.

Thanks,
SG

Unfortunately, Airtable doesn’t support global fields, but you can create a single record table that has your attachment in it, and then link to that record from all the other records. Then, create a lookup field that looks up the attachment field.
