Hi, I have been having an issue.  I used this video to work on this issue, but then got stuck: https://www.youtube.com/watch?v=s2rRRe0gE4o&t=107s. ( Signatures ) I have a database which uses a demographic table to store client information.  I have a subform called session subform that stores the information about each visit.  I want to collect signatures from the clients each time they come in, and have been using the files that you describe above.  I have created the signature form and linked it to the session subform, but when I run it, I get an the 2450 message, stating that Access cannot find the session subform.  When I debug it, it stops at the line "Forms!Session_subform.Refresh"  It does this whether I use an underscore for Session subform or not.  Any help would be appreciated.
