Code tags in the future please, Anonymonk (OP): without them, your square brackets become a shortcut <a href="...">...</a>.

For more information on the html variant used for markup here, see Markup in the Monastery ... and the very prominent notes on how to format a node beneath the text entry box in which you create a node.

...and yes, wsppan, re your observation about $row->[4] =~ m/Hardware/ or next;: that's how it should be... and would have been had Anonymonk read about how to post a node and heeded the instructions.
