Javascript error need help!

The shoppingsystem I've made works very well, only when I've added a painting to my shoppingcart and goto the shoppingcart and remove the painting, click the return shopping (dutch) button and try to add the same painting, the painting isn't added to the shoppingcart and IE 7 gives the following error, but I know the problem has to be with the function deleteItem.

The problem isn't there when I empty the whole cart, only when deleting an item.

I've tested it with ie, safari and firefox and only ie gives the problem.

Problem listed Bold is what I think the problem.

Here is the whole script:

</script>

And here is the line that isn't right (I think):

whattowrite += "<a href=\"checkout.html\" onClick=\"deleteItem('"+Xname[i]+"');\" >";

Hope someone can help me with this.

Java and Javascript are not the same thing. Moved.

sorry posted it wrong :)

function deleteItem(item) {
for (var i = 0; i < Xname.length; i++){
if (item == Xname[i]) { quant[i] = 0; WriteCookie(); break;}}
window.location.reload();}

That didn't do the trick. Could anything else be wrong?

I see nothing else wrong.

You say "IE 7 gives the following error" What is the error message?

You can check for yourself at the website http://www.artcreations.nl/schilderijen_dieren.html (its dutch)by adding a painting to the cart (voeg toe aan mandje), delete it (verwijder) (not empty cart), then continue shopping (winkel verder) and try to add the same painting, it won't add it. This problem only happends with IE, with safari and firefox this problem isn't there.

Someone else tested this also and said that with butterfly.html at line 100 an error was shown. This line is the calculate function, so I think that the problem lies there.

Hmm firebug says
f.total has no properties
[Break on this error] Saletotal = Saletotal * 1; f.total.value = round(Total);
dieren.html (line 169)

Where is your input control named "total"?

If you look at the function calculate, at butterfly.html (the top painting at dieren.html), I think that it's there where the is Total explained.

Because I can even work without the page dieren.html, so this page doesn't count (it should only contain the index of pictures).

I found this error with ms script editor: line 106 char 42

f.tOption819A.value = round(document.form.Option819A[document.form.Option819A.selectedIndex].value * 53);continue;

This could be the trouble maker. But don't how to solve it.

Anybody an idea???

I've found the solution, I had to made the hidden object visible and the page had to be equal to the item.

Thanks for all your help guys.
