Problem Fitting chain rings

Hi all I have a Cannondale rz 120.
I have gone cranks, but can't fit chain rings on the middle or a granny ring as cranks are to close to swing arm.
Any help pls thanks.

    From the pics I would say you have the wrong crankset for the bottom bracket, not 100% sure but from that angle it what it looks like.

    From his other identically titled thread the OP says that the chain line is perfect! Something is wrong.

    Wrong q-factor? If they know what that is?

    Looks like a two 2x crank probably need a 28t or less to fit that crank?
