(Solved)Ajax search boarder

This is a great plugin.
But here is my question, I see in this post, that some how I can alter fieldset to remove the border, but really it isn’t working for me.

I just want the border to disapear. I tried to add this to my css -
#ajaxSearch_input {
border: none;
}

But that didn’t seem to work, any clues on what I am doing wrong?

Never mind - That was dumb on my part - All I have to do, is set in the css
fieldset{ border:none;}
