simulink mask to pick subsystem

Hi, I am trying to use a mask to choose between 3 subsystem in my block. My block is a clamp that can clamp high, low or both. I made 1 block with 3 subsystem for each type of clamp but for the life of me I cannot figure out how to use a mask to let the user choose which subsystem is used. Hopefully somebody can help and steer me into the right direction.
