I see a simple number field defined with no auto-enter options.
I see it on the layout.
I see the value 1 in it.
So it is populated, at least on the current record.
What were you expecting to see that you are not seeing?
The top right screen shot is the data viewer.
The 1 is not populated, and my set variable won't set because it does not see it.
I see no reason in your screen shots why you are getting that result in the data-viewer.
Is this while running a script and using the debugger to step through it?
What version of FileMaker? If this is 14, maybe you've found a new bug.
