Hi can somebody help me out?

[Aybara]

Im working on a project and iverun into a brick wall.
I'm trying to code a cell, and what i want it to eventually do is basically:
if the value of cell A1 > the value of A2, then add 1 to B1
but every time A1>A2, just a 1 shows up, and every consecutive time A1>A2, i want it to ADD 1 to the value of the cell in B1, not just show that there is a 1 there.
can somebody help me fix it? thanks in advance
