Hi,

Some code for you at:
http://www.phpwm.org/pastebin/index.php?id=49

It assumes the text-areas have values in them to start with, and initially  
this is the ratio used for further changes.
If you change one value with the checkbox unticked, then the ratio is  
recalculated, so upon re-ticking it, this new ratio is used for  
calculations (experiment and see if that doesn't make sense...).

As one of the comments mentions, if this is going in anything larger than  
<something very small>, then using window.onload directly is probably not  
a good idea.
