In today adventure I have two container fields.
Field 1 is container with the staff signature as a jpeg.
Field 2 is a container on a vacation request form. A script will SET the vacation request signature container to the contents of the related staff signature container.
Sometimes it works fine.
Sometime I get a icon of a JPEG file in the Vacation Request container field instead.
If I go back to the staff card and cut&paste the signature back in and re-run the script it works.
But then the next time it is back to a JPEG file icon.
