One thing I have found is that when I try to do an attribute_filter on items in a select list you can't search on the text. If you look into the node using attribute(show) you'll find that 161 will be equal to a number (0,1, 2 and so on for each option).
so
(161,'=','Prayer Request Submission')
should probably read something like
(161,'=','0')
You can dig down to find which is which, or try trial and error until you find what number correcponds to each option in your select list.
