oscommerce multiple drop downs for attributes

I am currently in the process of revamping my oscommerce site. What I am trying to achieve is on the [login to view URL] page. I have some items with multiple option sets. So for instance there is a jumpsuit with regular sizes and tall sizes and both drop downs are displayed. there are a few problems I am encountering. 1. I have tried adding an initial attribute of "please select" in a couple different ways. None of which really work: a.I have tried merging in an array which requires the value be null, but when submitting the form that results in everything becoming null b. I have tried adding an attribute of please select to every product, but this displays the price next to the attribute. which should not be there. 2. Ideally the "please select" would only appear in the drop down when there are 2 or more drop downs only 3. when adding the product to the shopping cart the attribute "please select" should not show up in the cart. 4. if the user does not pick one of the 2 drop downs and trys to add to cart an error should appear informing them they need to choose a size. here is a link to the test page: [login to view URL] right now there is only 1 select now showing but you will get the point.
