So does that mean I would have to insert all of this code into the Script 
part? 
And for the ID, what would an example look like x.x like on the C:/ Drive or 
something like that.. I'm sorry, I'm just kinda confused
-------
 
set the name of me to "Play"
set the name of me to "Pause"
set the icon of me to 1000 ## the ID of an image you want to use

on mouseUp
if (the short name of me is "Play") then
...
else
...
end if
end mouseUp
