If you remove all but the AZList classify line from the collect.cfg file and rebuild you'll get the desired result. If you're really committed to doing it at runtime I'd suggest you scrap the set_navbarmacros() function and start over. As a simple case you could replace it with something like the following completely untested code. text_t navigationbar = "<a href="/gsdlmod?e=d-00000-00---off-0gsarch--00-0----0-10-0---0---0direct-10---4-----dfr--0-1l--11-en-50---20-preferences-JeanZz-Marc+Briennon--00-0-1-00-0--4----0-0-11-10-0utfZz-8-00&a=q">search</a><br> "; while (dochere != docend) { if ((dochere).metadata["Title"].values[0] == "Title") { navigationbar += "<a href="/gsdlmod?e=d-00000-00---off-0gsarch--00-0----0-10-0---0---0direct-10---4-----dfr--0-1l--11-en-50---20-preferences-JeanZz-Marc+Briennon--00-0-1-00-0--4----0-0-11-10-0utfZz-8-00&a=d&cl=" + (dochere).OID + "">titles a-z</a> "; } dochere++; } disp.setmacro ("navigationbar", "Global", navigationbar); ---- This discussion is a little too technical for this list. If you want to continue it you should probably use the greenstone_devl list instead. cheers, Stefan.
