Problems with Form

I created a form (I would attach it, but don't know how) and am having a number of problems:

1. When I hit the reset button I get the error messages:

a. "The value entered does not match the format of the field [ROI]"; and
b. "The value entered does not match the format of the field [MoEqCost]"; and

2. When I reset the form and enter a number in the “profit from Services" box I get the error "The value entered does not match the format of the field [Rate]" - and the form goes back to the “rate” field and changes it to another number (re-divides it by 100).

3. Other than that, the form seems to calculate properly (i.e., the formulas seem right).

Any help is appreciated.
