Product Listing Buy Now Issues

Hey all, looking for some expeirenced Zenner to help me with an issue I'm having, here is the site:
http://www.medievalme.com
I have installed the product grid template, and added the Options on Product Listing v2.0 so that they can select a size option and add to cart right from the product listing, here is the issue, if they dont select a size, I get a "Sorry, the product was not found.", with a link like:
main_page=product_info&cPath=208&sort=3a&action=add_product
If they click into the product info and dont select a product before adding to cart, the link looks like this:
main_page=product_info&cPath=208&products_id=1299&number_of_uploads=0&action=add_product
And they are presented with the nice error:
" Please correct the following:
On the Option for: Bracelet Sizes You picked an Invalid Selection: Select a Size".
Thanks in advance and any help is greatly appreciated :D

I looked at the rings on your site, and don't see an option for not selecting a size. You have the default size set at 6, and I was able to place a ring in that size in the shopping cart from both the product listing and product info page just by clicking the Add To Cart buttons with no error massages, so ...

Thank you for the quick reply, i forgot to mention try bracelets, I dont want to set a default size, i want them to select it. that will keep the returns for wrong size down :D

Your site won't load here now.

Oh noes! where is here? it loads fine is the US

It's back. Make sure your 'Select a Size' option is set as Display Only.

It is thats why it working the product info page?

I don't know. Is it set to Display Only ?

yes it is. i believe it has to do with the add to cart button instruction in the options mod, i was hoping someone else may have experienced it. there are 2 mods, the grid mod and the options mod so im just kind of stumped.

Not sure where you got the Options mod, but it sounds like whoever wrote it didn't include the function to check for a valid attribute that exists in the Zencart code for the product info page.

is there another product listing opions mod that you know of? as you can see, i would like them to have the option of adding the product to cart, without having to go into the product info page. the mod i am using, i found in a forim post here, just cant find the post again, the name is Options on Product Listing v2.0 (for stores with Add to Cart buttons for each product)
