addition
I have following function, but how can I do addition ?
if
f.Field1.value =2
f.Field3.value =3
f.Field4.value =1
then
f.Total.value =231, instead of 6
function update( ) {
var f = document.myform
f.Total.value = f.Field1.value + f.Field2.value + f.Field3.value
return true;
}
Many thanks.
Sorry, I mean I want it 6, instead of 231

function update( ) {
var f = document.forms['myform'] //- this part is not important
f.Total.value = +f.Field1.value + +f.Field2.value + +f.Field3.value
return true;
}

parseInt(f.Field4.value)

converted to numbers or the '+' operator will cause concatenation, not
addition:
