[ic] Custom looping tab -- [prefix-change] doesn't work

[interchange-users@icdevgroup.org (Barry D. Hassler)]

Hi,

I've been working on a custom looping tag, which for the most part =
works. However, I haven't been able to get the [prefix-change] tag =
portion to work in order to create groupings of the data.

Following I have my test custom tag, the test HTML file, and the output =
I get. If anyone can point out what I'm going wrong here, I'd greatly =
appreciate it!
