I am trying to use the sample code for ColdFusion SIM. I really want it to be very simple. I have done this with php but I am not an expert by any means with Cold Fusion. Basically all I would like is the user to enter in their amount they wish to pay and their account number then submit to the authorize.net's hosted form. I just can't seem to figure out how to let the user enter in the amount and account number. 

Any suggestions or help would be great - I am a beginner with ColdFusion so go easy on me :)
