Changed stylesheet height for header...but still not right

I followed the steps in the "How do I change the Header Image" tutorial and I was able to post my own header image. I also changed the stylesheet.css file as instructed...in my case as follows:

#logoWrapper{
width:760px;
height:143px;
background-image:url(../images/header_bg.jpg);
background-repeat:no-repeat;
}

On my website the width of the image is correct...but the height remains as before...it is too short.

Here is my url: www.myoldmanmovies.com/catalog

(I know that the image is slightly too wide...but I am currently concerned with the fact that I can't get the height large enough even though I made the changes to the stylesheet.css file.)

Thanks for your help.

Every file ending in .css is parsed in order - - You have

stylesheet_old.css

Change the .css extention to .old and you will see your changes in full - they are currently being circumvented by what is in this "OLD" file

Thanks much...that did the trick.
