Line 156, Column 35: ID "edit-submit" already defined.

input type="submit" name="op" id="edit-submit" value="Add to cart" class="form

An "id" is a unique identifier. Each time this attribute is used in a document it must have a different value. If you are using this attribute as a hook for style sheets it may be more appropriate to use classes (which group elements) than id (which are used to identify exactly one element).

The problem is that every "add to cart" and "edit-qty" submit button has the same id
any suggestions?

Thanks!
