What am I doing wrong with calculated fields

I'm making a character sheet for a homebrew game. In this game the driver of a vehicle adds his stat to the vehicle's state to get an aggregate stat. But the calculated field doesn't show up. I figure I'm doing something simple wrong. Here is the relevant block from the character sheet: <div class='sheet-3colrow'> <div class='sheet-col'> <b>Driver</b><br/> <lable>GUTS: </lable><input type='number' name='attr_Guts' /><br/> </div> <div class='sheet-col'> <b>Vehicle</b><br/> <lable>GUTS: </lable><input type='number' name='attr_VGuts' /><br/> </div> <div class='sheet-col'> <b>Aggregate</b><br/> <lable>GUTS: </lable><input type='number' disabled='true' value='@{Guts}+@{VGuts}' name='attr_AGuts' /><br/> </div> </div>

It works just fine for me when I simply paste your code into a blank custom sheet with no CSS. It's possible there's some stuff you've omitted that's causing problems. Also: you may want to correct your spelling; <label> has semantic meaning and default styling, while <lable> does not, and may get stripped for being an unrecognized tag.

Thanks! I'm starting to wonder if it's a browser setting or something on the client side. I'll try again and see if I can find more insight.

What browser are you using?
