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;

thanks - but it's still not working.
is that the right way to access it setting myfield to the field name and doing document.payments.myfield??

Try it this way

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



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?
