I would like the make the caption font larger on just one photo, but can't seem to figure this out. Here's what I have tried:

div#attachment_594 .wp-caption-text {
font-size: 1em !important;
}

div#attachment_594 p {
font-size: 1em !important;
}

Can someone provide the proper code for me, because I'm not sure what else to try.

URL is http://www.reapfoundation.org/student-resources/. Atahualpa version 3.7.3, WP 3..3.1.

Thank you.

I had to replace the image, now it is attachment_629.

that code is prefectly fine, your issue is with the CSS Inserts BEFORE it. You have a start comments '/*' but no end comment '*/' so that css is treated as a comment.

Wow, thank you. I guess I've just been staring at the same thing for too long.
