+1(@Value(END_MEASURE)-@Value(BEGIN_MEASURE))/5280
I am receiving a warning as follows
ExpressionEvaluator_5: Failed to evaluate TCL expression: (-)/5280
ExpressionEvaluator_5: TCL Error Message: missing operand at _@_
in expression "(-_@_)/5280"
FileGDB Writer: The `Mileage' attribute could not be written. The containing feature has been dropped
If I remove the division I do not get the error. I need to division to happen as the output needs to be in miles not feet.
thanks
Dan

One or more inputs are EMPTY/MISSING/NULL.
In this case "(-)/5280" both operands are so.
TCL cannot handle an empty attribute in a expression.
This is because any expression is basically a string that will be parsed. An empty attribute results in an "empty" spot in the string wich causes a parsing error.
You must test for EMPTY/MISSING/NULL on all operands before sending thme to the ExpressionEvaluator.
