May by this the problem?

System.Web.HttpException: Cannot have multiple items selected in a DropDownList. at System.Web.UI.WebControls.DropDownList.VerifyMultiSelect()

and the solution?

you have created a drop down list attribute for this product

when you created the drop down list, you have ticked 2 or more of the values to be pre selected


go to the item, to the attribute, click 'values' then make sure only one is ticked

(untick 1 then click 'update'  button for each
