The first screen shot below shows the problem I am having. The list lookup is allowing me to select the TAX1 value, TAX2 is saying "loading...". Once I select a value in TAX1, the option in TAX2 is only "please select value" with nothing to select.
The next screen shots are the control settings and the 2 lists I am using in the list lookup. The bizarre thing is that this worked previously on a different server, and although the below is just a test for the purpose of this post, I also exported the form from the old server and had the same problem.
Any help is appreciated
