DAMAGE is set to 0 here. However this is translated to 1+DamageBonus when evaluated on the outputsheet, which is actually wrong since it should be UDAM+DamageBonus. Since there seems to be no way to set DAMAGE to the value of UDAM, I suggest to make this
This way the Damage gets evaluated to an empty string, leaving the Damage field empty on the outputsheet. Since SPROP is set you can see what damage you should use instead.
