It may be cheating but I couldn't find another way to do it. I changed the input to include a 'Factorial' column.

I was using the iteration number, when I really only needed to look at record 1 each time. Once I corrected that to filter the numbers one at a time and fixed the size to Int64 I was able to get the solution.

The only way I could get this to work was to add a "Factorial" column to the starting Text Input tool that was given to us. I kept getting errors when I tried to include it in my macro.

This is my solution:

• Added support field to accumulate the factorial result.
• My macro features a lovely n! icon.
• I implemented error handling, if we request the factorial of a negative number or non-integer we get an error message on the workflow's Results messages pane.
• The output also feature an extra column, Error Message for any error processing the number.

Macro's workflow; the Yellow-Red arrows points to the error traps, and error messages.

After excution the macro gets a red-exclamation sign, and the Workflow results describe the errors.

Finally, the macro returns the Error Message column.

Pretty cool learning and understanding of Iterative macro

The select tool had to be used in the main workflow to convert the data type. I have tried outputting the values, however, in the macro workflow, it was importing the values as double.
