I have this, $metrics = variable_get('rbi_metrics_list_settings',array());, I have used this in 3-4 pages. And when I put in another file, when I wanted to see what's inside of $metrics , it said undefined function. I omitted it and it returned nothing. What seems to be the problem? Please help.

the tag is actually about variable_get(), but it's not available in the tags list. – CHi RiLo Dec 10 '12 at 18:16

What file are you using this in? – Charlie S Dec 10 '12 at 18:18
Also, in which function is that code used? – kiamlaluno♦ Dec 10 '12 at 21:46
