adjusting payment module

[zlack]

i want to adjust the cod to display a part of the total price in it.

 

this is what i added:

// Comfortcard Addon

       $blah = ($cart->show_total());

               switch ($blah):

                   case ($blah > 3000):

                       $cc_factor = 0.0209;

                       break;

                   case ($blah > 1500):

                       $cc_factor = 0.0224;

                       break;

                   case ($blah > 500):

                       $cc_factor = 0.0259;

                       break;

                   case ($blah > 200):

                       $cc_factor = 0.0517;

                       break;

                   default:

                       // Comfort Card not possible

                       $cc_factor = 1;

               endswitch;

             $blah2 = $blah * $cc_factor;



       $comfortcard_price= number_format($blah2,2);



// End comfortcard Addon

 

and it has to be added with the title:

 

    $this->code = 'permaand' . $comfortcard_price;

     $this->title = MODULE_PAYMENT_PERMAAND_TEXT_TITLE;

 

but i get errors when i try it. it doesnt look bad php code for me, but who am i :)

 

anyone can point me in the right direction?

 

thanks, zlack
