Drop Down Box

I have a form which contains a drop down box. I want it to be a required field, and I want the three options to be weighed as easily as possible (so I don't want one selected at the beginning). So far, this is my drop down menu:- ------------ Please Select ------------ Option 1 Option 2 Option 3 This would be for separate items. To give an idea 1. Warranty Options 1, 2, 3 2. Shipping options Options 1, 2, 3 3. Return Shipping Options, Options 1,2,3 Then on submit, if it was still ------------ Please Select ------------ they would receive an error code letting them know they must select an option. The shopping cart we currently use doesn't have this option, lame, I know. The software is by Turnkeywebtools, Sunshop.
