So, I tried making a sub-theme and it is not showing up!

I wanted to learn to do the CSS overrides so I made a subtheme of the theme I am currently using.

I copied over the CSS files attached to that theme into my sub-theme's folder, because I thought it would be the easiest way to see what the styles that are used in the theme are. I also copied over the graphics. I have a lot of experience skinning forums so I thought this would be a good way to learn, since that's how I originally learned to skin forums.

So!

This is what my subtheme .info looks like:


name = Tumbling After
description = Subtheme test
core = 6.x
base theme = acquia_marina
stylesheets[all][] = style.css
stylesheets[all][] = icons.css
stylesheets[all][] = local.css
stylesheets[all][] = style.css
stylesheets[all][] = icons.css
stylesheets[all][] = local.css

The name of the folder that the original theme is in is acquia_marina. They are both in the same directory,

However, when I switch to that theme, only the CSS styles show up and none of the information from the theme I am trying to use.

For reference, the .info for that theme looks like this:

Can anyone point out what I am doing wrong? Do I need a file declaration or something?

ETA: This is *only* happening when I use acquia_marina. It does not happen for any of the other themes I have installed, if I set them as the parent theme.
