Applying a formula to values entered in a form


I have set some formulas that should work with the values a user would enter into a form.

However, when I test this and submit a form, the forms data is entered below the cells that have the set formulas. 

I guess smartsheet thinks that this row is full and can't enter the form data here? Is there a way that I can get the form data entered into the rows that have the formulas in them? 

Note I am not trying to overwrite any cells. For example, the user inputs into the form the value 50 in column A, 2 in column B,  and I have set a formula in column C which equals A*B

Hope someone can help!
