Help with script

Hi, I need some help with this script I am using, I'd like it to be as following

First Click: Record
Second Click: Straight to overdub
Every other click be either play or overdub and also have the unmute function, if anyone can help that would be great :) I did try to work it out myself but every time you go to unmute it it just goes to overdub and not to play, Thanks, Ed :)


name RecNEW1


if mode = reset
record
else
Overdub
else
Play
endif


if mode = play
Overdub
endif


if mode = mute
play
endif

label sustain
if sustainCount = 1

wait loop
Reset
