This looks like a continuation of
If while code compilation problems ?

As to the error, how many tabs have you got open in the IDE ?

i got like 3 one of original osmosis1 project made a copy of it and another tab of osmosis1- copy and the third is a statemachinedemo

ok solved thanx man.
topic closed.
