GM6: A variable is refusing to change, EDIT: Solved

EDIT: Sorry about creating a topic. I solved the problem soon after posting this.

In the game I'm creating, at one point I assign a number (either 1 or 0) to a variable called dir, which decides the direction that an enemy moves in. There are invisible sensors that, when the enemy runs into, change the variable dir from 1 to 0, or vice versa.

At least, that's how it was planned. The code is below, and for some reason, dir doesn't seem to be changing at all.

The x value is changing visibly, so that code seems to work. It's not an inherent problem with the "dir" variable, though, because at another point in the code, I have it change from 0 to 1 without a problem.

In the segment of code that doesn't work, replacing "dir" with another variable also doesn't result in it changing, so it might be something wrong with the way I'm assigning the variable, but I don't see a problem.

Does anyone know what could be wrong with this?
