Is this still true - from help file ?? Tags are case sensitive, hence the following tags are not equivalent : "lounge light", "Lounge Light", "LOUNGE LIGHT". If so when do you get to find out the tags are not found - it compiles OK and no runtime errors. I have used this and I know the case not correct compared to the Toolkit DB SetLightingState("BED 6 CLOSED", OFF); SetLightingState("Bed 6 Open", ON); but no errors show up dave
