Discounts - Application To Specific Vendors Problem

Hi guys,

Your discount page - the buttons Discount Not Applied To Vendors and Specific Vendors - does not stick any info into the discount setting. These buttons flash twice each time with a list of vendors, you select them - and nothing happens.

The buttons Yes and No only works.

Need this rectified urgently.

To make things simpler, just give me an email address or somewhere private and I'll send you a temporary admin password so you can see for yourself.
