Jusst another side note:
you have to set the vars before you can use them.
you have this:
'M79.m1s
GetVar (550)
Code"#551=[#550/2]"
You need this:
'M79.m1s
Var1 = GetVar (550)
SetVar (551, (Var1/2))
'When ever you use a "Get" something, you have to set it = to something, OR, put the Get as the parameter of another function.
'for example
SetVar (551, (GetVar (550)/2))
