Multicards problem

[twantwan1]

My shop accepts creditcards with the multicards module but the order ammount is not correct when a customer goes to the

creditcard page. I think the problem is within "the fixed payment charge" module that i have installed, because this amount will not be calculated to the final amount that goes to the creditcard page

 

I use this mulitcards module:
