Nesting attribute calls

Ok on the official Pathfinder Sheet the damage field attribute modifier called repeating_attacks_$id_dmgattr. When calling this I get a string called "strength" instead of numerical modifier. there is an attribute called strength_mod. I want to dynamically call the dmg mod based on the attributes on the sheet for the weapon attack. I tried @{raskill killdare|@{raskill killdare|repeating_attacks_$0_dmgattr}_mod} but this does not work so how do you call an attribute in an attribute (nesting attributes)?

What do you get in chat with just [[@{raskill killdare|repeating_attacks_$0_dmgattr_mod}]]

No attribute was found for @{raskill killdare|repeating_attacks_LYcUrMo1DQxF2CxGy6r_dmgattr_mod}

The damage mod used for repeating attacks is @{repeating_attacks_$id_dmgmod} so perhaps you should try [[@{raskill killdare|repeating_attacks_ LYcUrMo1DQxF2CxGy6r _dmgmod}]] also; verify you have the correct ID if you are still getting "No Attribute was found..."

@{repeating_attacks_$id_dmgmod} is not the stat bonus on the sheet it is the field for mic bonuses like enchantment weapon focus, masterwork favored enemy, studdied target power attack mod ect. . If I put the strength modifier in that field then it get applied twice on the sheet macro which is kind of self defeating.
