I inserted the code below into the simple_matmult sample code. It appears to work as I expect it to but I get these error messages when compiling (what's up?):
WARNING: ASSERT(GetResultSymbol().IsValid() + mDataTypeValue.IsValid() >= 1) failed

{

}
BTW, if I compile just the code above (minus the ellipses), I get NO such error messages.
