Hello ... I have a form (Infopath Forms Services) and I had to implement Cascading Dropdown List Box (3). The primary and the next work well, but when I try to get the value of the second to the third filter, returns null.

Could someone help me?

It seems that the value of the filter does not get saved in the dropdown and therefore do not get it.

Thanks.

You'll need to verify that you have your filter set up correctly. If you have the #2 filter working correctly using the #1 value, the #3 should work in a nearly identical way. I'd review to make sure it was added correctly.

The other thing you will want to consider is the fact that #3 will probably need to filter against the values for both #1 and #2. If you only filter against the #2 value, you might be unexpected results depending on your data set.
