Hello guys, have a very weird issue and cant help but ask.
I created the Function with very simple math in it adding two REALS

Function always returns zero, same code works great with FB but not in a function.

FUNCTION DIVME : REAL VAR_INPUT num01:REAL; num02:REAL; END_VAR VAR END_VAR ------------------------ DIVME := (num01+num02);

When i call this function from the program the result will always be zero regardless of the value of two input parameters. Please guide me to solution. And yes CPU is running...
