Correct. At this point $lookuptable contains the value of dev_group.

That gives the correct value as well. But I wanted it as a variable
($lookuptable) ...
What I am trying to do is:
setCurrentDevGroup($this->Computer); // call function and get a device group
switch ($lookuptable) {
case "computers":
bla bla bla
case "printers":
yada yada yada
}
However, getting the inspired moment from your post, I tried
switch (setCurrentDevGroup($this->Computer)) {
case "computers":
bla bla bla
case "printers":
yada yada yada
}
And now this part works at least.
My understanding was that the function would return a value for $lookuptable
which was useable in the code above. This is incorrect then?
