Forumla Help Request: If one cell is higher than another, perform this calc. If not....

Hi Folks,

I am not having any luck trying to figure this out, so I figured I would ask here, as you are all the smartest people I know.....

The attached pic is a sales tracker/commission calculator I am working on. Here is the scenario.

If a sale is completed at or above the target margin rate, then the formula I need to calculate is:
Base Commission Rate X Secured Volume X Secured Margin Rate Kicker

However, if the margin rate is below the target, the calculation must be:
Base Commission Rate X Secure Volume

I have not been able to figure this out after a few days of trying. Can anyone help me please?

Thank you.

Joe
