I have added a very simple PayPal form with a selector for 2 payment options on this page: http://texaswatsu.com/private-sessions/ (low down on the left sidebar). As you can see what should appear as one selector field with 2 options in a drop-down selector is showing up as 2 separate items. Neither item may be selected so a purchase cannot be made.
I suspect it may be due to some css styling (I haven't made any changes to the original css) but have not been successful in finding it.
Your help is appreciated.
