First of all be kind, I am new to javascript.
In the following page, can you tell me if I have defined the ObjTyp and
the ObjTypeCnt incorrectly. And if that is correct, why can't they be
seen from within my function ChangeSearch? Yes, the ObjTyp and ObjTypeCnt
are generated by a php script.
Thx in advance, Terry
