I'm a little confused and can't figure out how to capture a script step that has a calculation using an the "Evaluate" function with an invalid argument.  For example if I pass an argument that is not quoted and does not represent a valid field name. 

 

In case I'm not describing this clearly you can check out the example file.

 

Thanks

Feed the expression to EvaluationError() first.

That was easy!

 

To capture a syntax error I guess I should use 'EvaluationError (Evaluate (expression) )'

Better don't guess; as I said: http://fmhelp.filemaker.com/fmphelp_12/en/html/func_ref3.33.5.html#1027784
