How do I make my dropdown #1 multiply by dropdown #2

When someone chooses the "5 clicks" package from the first dropdown, theyll then go to the second drop down and choose how many days they want 5 clicks.  So dropdown 1 needs to be multiplied by dropdown 2.

If you guys can make this happen, Id be greatful.

Here's the form --> http://form.jotform.us/form/42156707594158

Hi,

I cloned your form to test it and it appears you are really close.  You have already added custom calculation values to your drop down fields, now all you need is a custom calculation widget to perform the calculation:

The widget can be found in the widgets section of the form builder.  Here is my cloned version of your form so you can see what I added:

You can also pass that calculation to the payment form:

Please let us know if you have any further questions and we will be happy to help.

Thank you for using JotForm!

awesome bud, now how do I make the calculation appear in the "cost" box.  Right now, dropbox 1 x dropbox 2 equals 3 in the calculation box, but in the "cost" box it all equals 4.  

So I think I need the "calculation" box to send its calculation to the "cost" box.  How?  :)

SOLVED, ooo, ok, I clicked on the "total" box, above "cost" and changed the equation.  I deleted the equation and added "calculation"  Now the "cost" box shows what the "calculation" box shows.

Thanks, you guys are awesome!
