I'm happy to email my test if you want or you can type it in to your own test file
Thank you for your post, and I apologize for the late reply.
I am unable to reproduce the problem on an iPad with iOS 5.0.1 running FileMaker Go 1.2.4. I get an error message:
"Failed to open "cnsbarcode://scan?method=camera"
If you haven't updated to FileMaker Go 1.2.4, do so at this time and try again. If you still get a crash, create a new database file and execute the script.
Try closing out all other applications in case there is a memory conflict.
I know it has been almost three months siince you first posted, so if you have since found a resolution, please post here so others that encounter the same symptoms can benefit.
