Retrieving cell value and posting back

Summary:

Hi, I have one member called "Counter->No Project" I want groovy to pick value from it and add 1 and post it back. I basically want to use this counter while creating dynamic members (See the code below)

newmember = "${Year}"+"-"+"${NDept}"+"-"+"${Mall}"+"-"+"${CBS}"+"Counter"
