1 radio button group that inserts data into a field that is used in 1 of 3 calculations

I have 2 radio buttons that are grouped and depending on your selection a data field is auto populated from the data in another field. The field that is auto populated is part of a simple yet complex formula to solve an equation, where some of the data is recycled. I had it working for the most part at some point today, just the last equation was kicking out the wrong answer. For example; the last equation would be something like .035x100=3.5%; but was giving the answer of 350%. I saved my progress even though the equation wasn't correct and when I opened it again to work out the issues, nothing worked anymore. I can get the radio buttons to autofill correctly but, that's it. Please help!?!?!

I attached the form and a couple of screen shots. Right under "Remarks" on Page 2 is the formula. Can someone please tell me what I'm doing wrong??
