1E AD&D Character sheet weapon rolls = 0?

Attack and DMG rolls are coming out 0 no matter what the dice say, when I roll them from the character sheet with a modifier. Stat bonuses are ignored (ex: I entered +1 DMG for STR:16  It ignores this entirely.) If I enter a ToHit bonus or DMG bonus in the weapon description, that roll will register zero. This is independent: If I enter one but not the other, only the modified values will roll zero. Hope that's clear?

Shoot. Forgot to say, if I enter the modifier when prompted before the roll, the same thing happens. Zero.

(Moving this to Character Sheets until it is proven this is a Roll20 issue rather than a sheet issue)

Stat bonus for STR is not used to auto-calculate the repeating weapon damage fields.  Use it as a reference and adjust each weapon attack To Hit and damage as needed. Try removing "+" for weapon bonuses since the macro-text already includes it.  ie a +2 bonus should just be "2".  You can use "-" for penalties though. ie "-2"  I'll see if I can make an adjustment to the sheet to avoid any confusion or errors.  Thanks
