Okay I get to the part where the tutorial says to make the rectangular marquee. Then hit ctrl+click on the layer with the rectangle in it, then hit ctrl + Shift + I to invert the selection then hit DELETE, to get rid of the black color on the outside of the rounded edge box in the 80 x 80 layer. Which delete am I suppose to be pushing? And for some reason no matter what I do, it won't delete the edge around it......Help?
