Integer < Integer returns False when it should have returned True.

Doing a classic jump blueprint but yesterday it worked well. Today I changed the character it’s applied to and while everything works good, double-jumping doesn’t work. I check the boolean value to see that 0 < 2 is a false statement. Excuse me what?

Edit: ok my miss, I didn’t set the Max Jumps from character tab in character(self) as I open the character blueprint to 2.
