How to limit Option Attributes to 1 qty?

I added an Option drop down to a product that has different size attachments - so they can choose the size they want.

Problem is the product quantity is limited to one. But you can keep adding the item with different sizes to the shopping cart. Anyway to fix this? :huh:

Set the Maximum to 1 instead of 0 ...

Now only 1 can be added to the cart ...

Also set the Quanty Box to be hidden, and save steps on this ...
Products Quantity Box Shows: **No, Do not show Quantity Box **

I am thinking you should fix all of these, but in particular $24 ... :smile:

Arrgh! :blink:

The first step in the Admin worked great. I then added the line from #24 and now it does not even go to my cart on any item. Just a blank page.

I removed the line (in both places) and it still won't go to my cart.

For reference the lines were located at 2801 and 2871

What can I do?

Now it is worse I tried to log into Admin and get this.

:smile: I think it's ok now.

I extracted my backup and found the original shopping_cart.php file - renamed the old one (just in case) and uploaded my backup.

So far everything seems to be fine.

I don't know what happened with the other edited one, as I triple checked that it was the same when I resubmitted it without the code change. :unsure:
