PLZ help PS kicking my A$$!

ok here is another problem im havig w/ photo shop cs2
im doing this tut on making a "simple" sphere,

so far ive done this: Make a new image - 100 x 100 pixels - transparent background.
Create a new layer. Have white as your foreground- and black as your background colour.
Create a circle with the Elliptical Marquee Tool (hold down the shift-key when making the selection to create a perfect circle).
Now select the Radial Gradient Tool, and fill the selection

i get to the gradient par of this but when i try to apply the gradient i get this error "Could not use Gradient tool because the content of the layer is not directly editable" wtf am i doing wrong/ what in god's name dose it want from me?

Its saying the canvas or circle you have is too small. Here's a tip. Create a new image but of bigger canvas size. Eg, 500x500 at 72 DPI. Then make a circle and use the radial gradient.

Thx for the help, but it still says the same thing ='(

Did you use the eliptical "MARQUEE" tool or the eliptical "SHAPE" tool?

You'll have to use the Marquee tool to be able to fill it with a gradient
