Use of choice_filter and nested repeat

I am trying to use choice_filter in nested repeat but it does not work. I tried to cascade with district and upazila in nested group.
I am using ODK Collect v1.30.1

Hi @Mdabdullah_Rp
I think you made a mistake constructing indexed-repeat function for that nested group.
If you have a structure like this let's say:

begin_repeat group1
    begin_repeat group2

the syntax should be:
indexed-repeat(${question2}, ${group2}, ${indexOfGroup2}, ${group1}, ${indexOfGroup1})

in your form you don't fallow this pattern.
