Geocities is so touchy. I have a site on there too.
www.geocities.com/adpibetatau and
www.geocities.com/alphadeltapialumnae
You just have to check and double check your links on the index page for each word you want linked. I get errors all the time. It must just be since it is free! Who knows! But overtime my sites have worked out fine...just work through the kinks and be patient!
