I create new query for create Sum in any fields and make new field for amount that sum fields, but when i create new field for amount when i run the query it always as me to "Enter Parameter Value?" what problem with new field for amount?. In any field that we use Sum it auto to create field name with SumOf...., unless i change to new name in the new field for amount it always as for "Enter Parameter Value?" also. How i fix this problem.
Thanks in advance
