i dont know why its not working...hrm

Try using this instead:

#cat A:link, #cat A:visited, #cat A:active {
COLOR: {categoryfontcolor};
TEXT-DECORATION: none;
}
#cat A:hover {
COLOR: {categoryfontcolor};
TEXT-DECORATION: underline;
}

That will give it an underline ONLY when you have your mouse cursor over the link.

i thought he didnt want any underline./..??

He didn't want one for when it's not hovered over. Taking the underline out when hovered is bad because it will be harder to determine whats text and whats links to some people.

If you still don't want underlines at all after hovering use this:

#cat A:link, #cat A:visited, #cat A:active {
COLOR: {categoryfontcolor};
TEXT-DECORATION: none;
}
#cat A:hover {
COLOR: {categoryfontcolor};
TEXT-DECORATION: none;
}

tru....i thought about that...good going
