Parse Error at char(9): An expression cannot end with an operator (Expression #1)

Hey!

I want to calculate two double values

I build an marco with a listbox tool for my change calculation.

In my  listbox property I have enter:

added to:+
multiplied by:*
divided by:/
subtract to:-

Then I build a workflow with my macro has inserted.

If I try to run this workflow I got the exception:

Error: masmarcro_20150915_2 (3): Tool #3: Parse Error at char(9): An expression cannot end with an operator (Expression #1)

But why?

I did not understand the error message.

I have add my build_order.pdf how I set the values an parameter.
