Is there a way to change the signature container to a white background.
You can specify either a white fill color for the field.
I want to use it to draw on it then save it. Also everytime I click it again it erases the previous signature/drawing. Is there a way to have the option to keep it or erase it.
This container field is in a table. You should capture each new signature in a new record in that table. To "erase it", you can delete the record or possibly revert it depending on the design of your layout.
You should really ask this question on the FM GO forum (see tab at top of this screen) as that's where you can talk with other GO users that may have already set this same feature up in their solutions.
