Form calculate

[tykst]

hi guys, I'm trying to get my form to calculate sub totals, add the subs and multiply the grand total by $15. And onsubmit, sends the calculation + some other user information... I got this working calculation code from somewhere but when put together with other fields, it malfunctions!! I need to do this but I'm a web designer and know nuts about anything beyond HTML... it'll probably take a programmer to solve it within 5 minutes but i've been at it for days... please help me look at he codes beneath?

<!-- --------- the script ---------->

function initZero(obj){
if (obj.value=="") {
obj.value="0";
}
}

function calculate(){

var frm = document.frmOne;
var len = frm.length;
for(x=0;x<len;x++){
initZero(frm[x]);
}

A1 = document.frmOne.RED_XS.value;
B1 = document.frmOne.RED_S.value;
C1 = document.frmOne.RED_M.value;
D1 = document.frmOne.RED_L.value;
E1 = document.frmOne.RED_XL.value;
F1 = document.frmOne.RED_XXL.value;
sub1 = parseInt(A1) + parseInt(B1) + parseInt(C1) + parseInt(D1) + parseInt(E1) + parseInt(F1);
document.frmOne.RED_TOTAL.value = sub1;

A2 = document.frmOne.WHITE_XS.value;
B2 = document.frmOne.WHITE_S.value;
C2 = document.frmOne.WHITE_M.value;
D2 = document.frmOne.WHITE_L.value;
E2 = document.frmOne.WHITE_XL.value;
F2 = document.frmOne.WHITE_XXL.value;
sub2 = parseInt(A2) + parseInt(B2) + parseInt(C2) + parseInt(D2) + parseInt(E2) + parseInt(F2);
document.frmOne.WHITE_TOTAL.value = sub2;

A3 = document.frmOne.BLACK_XS.value;
B3 = document.frmOne.BLACK_S.value;
C3 = document.frmOne.BLACK_M.value;
D3 = document.frmOne.BLACK_L.value;
E3 = document.frmOne.BLACK_XL.value;
F3 = document.frmOne.BLACK_XXL.value;
sub3 = parseInt(A3) + parseInt(B3) + parseInt(C3) + parseInt(D3) + parseInt(E3) + parseInt(F3);
document.frmOne.BLACK_TOTAL.value = sub3;

A4 = document.frmOne.BLUE_XS.value;
B4 = document.frmOne.BLUE_S.value;
C4 = document.frmOne.BLUE_M.value;
D4 = document.frmOne.BLUE_L.value;
E4 = document.frmOne.BLUE_XL.value;
F4 = document.frmOne.BLUE_XXL.value;
sub4 = parseInt(A4) + parseInt(B4) + parseInt(C4) + parseInt(D4) + parseInt(E4) + parseInt(F4);
document.frmOne.BLUE_TOTAL.value = sub4;

// initalize the total
grandQty = sub1 + sub2 + sub3 + sub4
document.frmOne.qty_total.value = grandQty;
document.frmOne.cost_total.value = grandQty*15;

}

please mention the errors you are getting, or post the link to the page where you have this implemented

here's the attached form.. if it helps.
it's a htm file but I've changed the extension to .txt to post it here

[Khalid Ali]

the first errors I seeare these. replace these 2 lines

document.frmOne.qty_total.value = grandQty;
document.frmOne.cost_total.value = grandQty*15;

with these 2 lines

document.frmOne.QTY_TOTAL.value = grandQty;
document.frmOne.COST_TOTAL.value = grandQty*15;

for submission.you will have to let me know the error you are getting.I can not guess what is the error in that respect.

Unbelievable! All this while, it was juz an uppercap/lowercap issue?? >___< Those hours of sleep I've wasted trying to figure out! Thank you sooo much, you're my saviour!! After changing those two lines, everything's working fine. Thank you!! ^ ^

:mad:
Give them something good and they will ask for more.

Now the follks I'm doing this form for wants the following conditions:

1) when the user clicks CALCULATE, fields that were empty remains empty instead of showing a "0"

2) onClick submit, fields that were not filled in will not appear in the sent information at all.

:( what do I do?
