I have a data view web part set up in CrossList mode to create a rollup. This rollup will span multiple sites, and is rolling up items from Tasks Lists on those sites. What I am having trouble doing is getting a count of lists that it is rolling
up. I was trying do a count of list IDs, but it gives me the count of all the tasks, not the lists. I need a way to do a count of distinct list IDs or something similar that will give me what I'm looking for. I should say I'm not that great
with xsl, so maybe I'm missing an easy solution. Any advice would be appreciated.
