How to do dmg-rampup properly

[Melonpizza]

Hello fellow internet stranger(s), im currently working on damage rampup on a weapon for balancing reasons. But the code i did wont work (in decorate)

brrr:
SMIN A 0 a_gunflash
SMIN A 0 a_Checkrange(100,"brrrdist",false)
SMIN A 2 a_Railattack(20,5,true,none,"Grey",rgf_nopiercing|rgf_silent,2,"SchisaBulletPuff",14,6,950,20.0,1.0,1.0,none,11,0,0)
SMIN A 0 a_playsound("Mininbang",3,1,false,false,false)
SMIN A 0 a_Checkrange(100,"brrrdist",false)

(Code for a minigun) it only will do 20 damage, regardless if thr target is further away then 100u

Thanks
