shopping cart and paypal help (scripts etc)

[guydewdney]

got a 'simple' one... lol

Got nopcart as a shopping cart setup on my stepfathers website.

currently setup as 'print off order form' to order.

want to add paypal to it.

BUT - it appears that half of the nopcart.js file is missing - presumably as it wasnt needed - but i know nothing of this stuff, so i cant just add script in willy nilly..

this is the nopcart.js file:-

function CKquantity(checkString) {
strNewQuantity = "";

for ( i = 0; i < checkString.length; i++ ) {
ch = checkString.substring(i, i+1);
if ( (ch >= "0" && ch <= "9") || (ch == '.') )
strNewQuantity += ch;
}

if ( strNewQuantity.length < 1 )
strNewQuantity = "1";

return(strNewQuantity);
}

function AddToCart(thisForm) {
iNumberOrdered = 0;
iNumberOrdered = GetCookie("NumberOrdered");
iNumberOrdered++;




etc etc - does this make sense to anyone? If it does, and you can help an idiot out - ill post more of the problem.
