Bose soundtouch and Alexa

Looking for some help on getting Alexa to control my bose soundtouch equipment, I have successfully got the power on / off to work, BUT i cant get the preset selection to work

My BOSE.items

Switch Bose1_Power “Living Room Bose Power: [%s]” [ “Switchable” ] { channel=“bosesoundtouch:device:B1:power” }

Number Bose1_Preset “Living Room Bose Preset: [%d]” [ “Selection” ] { channel=“bosesoundtouch:device:demo:preset” }

Bose.things i assume is correct as the power on/off works

Anybody got this to work ?
