function

[tintin_taurus]

:confused:

I try out tis function but then it did not somehow add all the numbers up..

function compute() {
with (document.num) {
travel.value=len.value+y.value+overtravel.value;
}
}
all it did is tat.. example i enter in 2, 1 and 3
instead of adding all up which is 6,
the answe tat they give me is 213.. which is huge different

Need help desperately
