Releasing Cue after effect has finisched.

I am trying to get a que working that releases once an nshot effect has finished. 

I am haveing trobble when needing to set a defult value in the cue. I jsut defults to that value once the effect finishes. 

example: 

ramp effect for pixlemap x-pos going from 0 to 100 

after the nshots have completed xpos defults to 50% since it is set to that and cue dosent release.

dose anyone know of a nice why to solve this issue without haveing to come up with wait times for the effect?
