For the first time, I've been playing around with Jeff B's Woofer Box Model and Circuit Designer both at work (during my lunch hour... I swear) and at home. In both locations, I haven't been able to get any data to display in the graphs. The graphs show up, just no data plotted.

I've put in the parameters for a specific woofer and it calculates similar box volumes, vent lengths, etc as in WinISD and Unibox, so it appears I'm doing the data input part correctly. Is there another step I need to do (or problem to correct) to get graphs, or is it likely to be some problem with Excel and/or my computers?

At work I have Excel 2003, SP3. At home I have Excel 2000. I'm running Window XP in both places.

Thanks in advance!
