This is what I've done so far. I have many categories/subcategories that need custom headers (for banners, category title, etc). I've used the "header" field found by editing the catergory/subcategories and inputting the customized header html there. Included in the header html is the nav bar. Now I'm wondering, what if the nav bar changes? I'll have to go edit all the categories all over again. So, I went in to Template Globals and added the code "co_navbar" and in the description I put the nav html. I added <%co_navbar%> in the header field where the navbar html was before and saved. Didn't work. I went back to the Globals and changed the html to an URL where the navbar.txt file is located, thinking that might work. No, didn't work either. I deleted <%co_navbar%> in the category header field and replaced it with the url to the navbar.txt file. Still didn't work. I'm sure I'm doing something wrong here. Can anyone help?

Thanks in advance!
