Exception while trying to add new Product-Vendor details. [ For input string: "" ]

 Anyone else getting this?  When attempting to change pricing on an item in"Asset Management-Products"  This item is used for 3 different suppliers and when I tried to change the price for one of the suppliers this is the error message received.  It did, however, remove the price that was in there and put it back to $0.00.
Thanks
