Hi. I'm trying to add some horizontal and vertical edges to a face but when i click on the face and click "add devisions" set to linear 4 10, it doesn't do anything.

when i try exponential i get the pic below but that's not what i want at all.

I'd love to start over but i want to know what this problm is so if it happens when i 'm further than a cube i can fix it myself.
