Item script help

[rans 7]

Hi there.

Can anyone tell me which script command should i use if i want to check like if he is equipping 2 cards.

I only know the if(isquipped(xxxx)) but i don't know how to make it count on example if im wearing 3 doppel card it would grant me max atkspd. 

TY

nvm solved:
 if( isequippedcnt( xxxx) )
