The parameter list allows you to select the Isight
input and output parameters that you created earlier in the Excel component.
Selecting n from the list of parameters means that you will loop on the
value corresponding to the number of coils in the spring.

When you select the For Loop option, you can also specify a start
point, end point, and increment for the parameter that you have chosen
to loop on. In this case you are going to vary the number of coils in
the spring between 5 and 50.
