0

Short version:
$count in the code below seems to be 0 even when it shouldn’t, why?

Long version:
The other day my boss said “X has made a program to store schematics in, and released the source code. put this on our intranet” So i got around to figure everything out. The source was about 25 different .php-files and a picture describing database tables and relations. Is the error related to the piece of code below or does it have to do with something else?
Maybe I’m just tired from a long week and just don’t see it.

Code:

    <?php
/**
* new_series.php
*
* Generates all the forms for creating a new series and machinenumbers.
* One form for selecting what drawinglists the serie should contain.
* One form for selecting what drawing the serie should contain and select
* a serienumber.
* One form for selecting machinnumbers.
* One form for listing all drawings with all information and number of
* copies that should be printed.
* This is where the function to automaticly print all drawings should be called
* when that function is availible.

112: $count=count($drwlist_rowID);

What is $drwlist_rowID? It seems not to be defined…
