How can I read a value from a complex adaptive map?

I can read the values ​​if the body only has input text. In this case, there is a column and a column. When I filled in all the input and clicked the submit button from the emulator, I get no value.

Platform: .Net C #

Below I have shared some information about json map. Could you please help me to solve this problem.
