HTML5 Canvas & JavaScript - Need Help!

[Mammoth]

Alright, so I am making a map editor (mostly for learning), and I am at the point where I have click detection to find the tile that you clicked on, but when I try to make that single tile change colour to blue, the whole canvas fills with blue – as if it's filling every tile with it.

I only want the tile that I clicked on to change to blue. I already have the detection going on, and my "if" statement at the end works wonderfully. I'm not sure why the whole thing turns blue upon click.

Any help?

fillRect is what you want

Ah… that works beautifully. Thanks! Seems like a simple mistake.
