[AccessD] quick help needed

I just rolled out a new program yesterday and it worked quite well. I tested it and ran it through the course, and everything seemed to go as planned. I am fully aware that no matter how much you test something, as soon as you turn it over to the user(s), they WILL find the bugs, and I warned them that this will happen and we'll work through anything that comes up...it is easy w/this group, because they literally sit right beneath my office...we share a server, a switch, everything is the same, so I can basically mimic everything they do.
 
Well, it was installed yesterday. After installing it, I watched as the user entered her first bit of information. It was pretty uneventful, but we did get a bug...my fault actually, as I borrowed some new code that I liked for my nav buttons and I wasn't really comfortable w/it...that was bad enough, but this actually made some previously entered code buggy as well. All in all though, nothing huge and I just had some little bugs to fix. And, they had some customers come in throughout the day, and all went well.
 
BUT...after I left for the day, they got another customer and the program would not cooperate. Basically, this program takes in student information and prints a certificate that they take to their schools. This certificate, which printed previously, no longer found information off the form. It prints, but it is blank where any information from the form goes...it prints from the current form. Now it says, "Run-time error '3021' No Current record."  And, that is not all the time...what they hey?! There IS a current record...it is the one on the screen that I am pushing the button for!
 
Any clues here would be greatly appreciated...I'm a bit under the gun here. 
 
Thanks!
