Through inputting, these variables are defined.  

vs   (this is a percentage)

Week_Gross    (this is a decimal generated through a formula by adding several previously inputted numbers)

Guarantee  (this is an integer)

In plain speak, the result I want is

If vs * Week_Gross is greater than Guarantee, then output vs * Week_Gross, otherwise output Guarantee.

I have generated the following script, but it doesn't generate correctly.

If((input.vs*input.Week_Gross)>input.Week_Gross,(input.vs*input.Week_Gross),input.Guarantee)

Can you advise?

Because Week_Gross is a formula already generated by adding several previously inputted numbers, do I need to put those in on their own instead?
