@gunrunnerjohn, if you look at my edited example from your thread, you will see that the URL encoding around "special" characters is not being handled properly by Crowdstack, in this case the "[" character instead of the proper URL Encoded %28 character (which interestingly enough is a "(" character). Bottom line, they have something screwy going on.
If you want to geek out on URL Encoding: https://en.wikipedia.org/wiki/Percent-encoding
