is t possible to add an error message when setting up an Add To Cart button with a drop down menu - so that if the customer clicks the button without selecting an option from the drop down they receive an error message BEFORE they are taken to the the PayPal cart page?
The way I did my checking and errors were in jQuery BEFORE SHOWING the button ..that was the only way that I could figure, else you have to jump through hoops with their $^itty Error stuff.
