    function help

    can someone help me with teh following function I am trying to write.

    my code:

    function PaymentsDelete(i){
    if(document.payments.deleteme.checked){
    alert('delete');
    myfield=amount+i;
    documents.payments.myfield.value=0;
    }
    }

    What I want this to do is to take the i passed in and set the field in the payments form name amount and i to 0.
    In other words if i is 1 then the script should set payments.amount1=0.

    can someone help me get this working. Now it seems to be ignoring the statement.

    You may just have missed a typo in this line

    documents.payments.myfield.value=0;

    remove the s from documents to give you

    document.payments.myfield.value=0;

    Try it this way

    PHP Code:
    function PaymentsDelete(i){
    if(
    document.payments.deleteme.checked){
    alert('delete');
    myfield="amount"+i;
    document.payments[myfield].value=0;
    }

    or this way depending on your preference


    PHP Code:
    function PaymentsDelete(i){

    myForm=document.forms["payments"]

    if(
    myForm["deleteme"].checked){
    myForm["amount"+i].value=0;
    }

    err what type hase the control "deleteme". A checkbox? If so, I guess that you have a collection of checkboxes with the same name. In this case you should circle through the collection or use the index. Can we see your HTML code?
