How do I program a custom character sheet to track hit points in a way compatible with token bars?

This is probably a really easy question to answer but I've been searching and googling and I haven't been able to find it. I have hp_current and hp_max as attributes but i don't know how to combine them into a single bar-compatible attribute.

Each attribute has both a current and max rating, you dont need to create two separate stats.  If you want to display and use the max value of an attribute, add _max to its name, So, you'd create a hp attribute (not hp_current), and create a second attribute hp_max.  The second attribute will actually not be a true second attribute, but will be the max value of hp.

Generally, the sheet will automatically generate a "_max" value for any attribute you have.  If you have your sheet active, put a value in hp_current and look at it in the Attributes & Abilities tab, I bet there will be a max value slot set up for it.  It will be "hp_current_max", though, since hp_current" is the base attribute.  Basically, the names have to be identical except for "_max". Edit:  And I took too long typing my answer up!

I knew it was something that'd be obvious in retrospect but in all my googling I never saw anything specifying that _max was a modifier. Thanks.
