I wish all AEL problems were this easy!

The complaints are coming from the fact that you have to call the
built-in function
TIMEOUT from within the ${ } notation, or its equivalent... 

To do this you need an app call to put it in...
Try:           Set(TIMEOUT(absolute)=7200);
instead.

And, Function names (last time I checked) are case sensitive, so the
line:

theChannel=Cut(AVAILCHAN|-|1);

Should most likely be:

Set(theChannel=${CUT(${AVAILCHAN}|-|1)});

So, don't forget to wrap your variable names in ${} and don't forget
that
the first argument to the app Set() is treated as a variable name
without having
to have it wrapped in ${}.
