    I believe this is C++ but please correct me and redirect if necessary.

    I am pulling this code from a former employee. This is for a credit EFT Contract where when you swipe the card into a text field, the following values are inputted; Card Type, Card Number, and Expiration Date. I had to add Discover to our contract to which I have added successfully for the card type and card number but i cannot get the expiration date to work at all.

    This is my current code for Expiration Date. CCEnter is for the card swipe.

    inputex = this.getField("CCEnter"); cardex = inputex.value.toString().substr(20,35); found = 0; hold = 0; i = 0; for(i=0;i<35;i++) { test = cardex.toString().substr(i,1); if((test == "^") && (test != " ")) { found++; if(found == 1) { hold = i+1; i = 45; } } } typeOfCard = ccnumber.value.toString().substr(2,1); newAmex = ccnumber.value.toString().substr(6,1);

    if((typeOfCard == 3)&&(newAmex == " ")) { ccEx1 = cardex.toString().substr(hold,2); hold += 2; ccEx2 = cardex.toString().substr(hold,2); event.value = ccEx2 + String('/') + ccEx1;
    } else { ccEx1 = cardex.toString().substr(hold,2); hold += 2; ccEx2 = cardex.toString().substr(hold,2); event.value = ccEx2 + String('/') + ccEx1; }
