Stock size in BOM (SW 2007)

[jkies]

I am trying to get SW 2007 to display the part stock size in the drawing BOM
("Thick" x "Width" x "Length"). I have been using MDT for eight years and am able to do this quite easily.
I have established a part template with the necessary custom properties, but I am not familiar with this program well enough to know what the formula is. I have modified the BOM to have a heading called "Stock Size".

System Info: Dell Precision P4 Dual-Core, 2 GB RAM, Windows XP Pro

Thanks in advance.
