Hello dear friends

Anyone here who could give me a hand with this project?

The problem is as follows, I have followed the letter according to the attached tutorial. And the result is as follows according to the image that is captured, I have already verified the code several times but I can not find the problem.

unbound_subreport.zip

Apparently an infinite loop is generated, as you can see in the image.
