I have installed and enabled select_or_other. The test example works perfectly and is just what I want to do. But I can't figure out how to implement it with my Ubercart product.
I have a product "Donate". It uses an attribute called cash donations with options of $25, $50, etc. Currently I have the "Display" type set to select box. However, I want to add an "other" option where the user can input a different amount. Is this possible?
