Hey Nick, thanks for your input I really appreciate it.
Unfortunately I didn't manage to get that code working either.
I'm trying all different combinations and nothing seems to write the machid to the database.
Have you got any other ideas? Ill be working on this most of today, ill post an update if I find a solution. Otherwise I'm really keen for any ideas you may have

Thanks again.
*Edit* Still no success

Though the code is working somewhat, I changed:
$res->machid = $machid;
To
$res->machid = $summary;
With this in effect the machid is successfully updated to the summary column in the table.
When
$res->machid = $machid;
is in effect NOTHING happens... no update...
*2nd Edit* Hey Nick no success today

seems like when you update a reservation the machid is updated also which I think may be overwriting the machid change field in the reservation page... Really looking forward to your input this is all we need to launch it

Though there are hundreds of things we are planning to do and help contribute.
