Comparing exact block data with Procedures

I'm currently trying to make an axe that cycles the wood type when you right click a plank. So like if you right clicked oak planks, it would change to spruce, spruce would change to birch, etc. The problem is I don't know how to make procedures detect the exact version of plank that I'm right clicking. Whenever I right click with the axe, no matter what type of plank it is, it always detects it as the first thing I've put in the if else (Image below) and runs the first if statement. I don't know how to make it able to detect the exact type of planks I'm right clicking.
