Dynamic project problem: Child data is not working

Dear All,

I am using a dynamic data project. My parent dataset has worked following the guideline that I derived from this group. However, I could not upload the child data. Could you please support me regarding this. Here is my file for your support.
branch level_urban.xlsx (72.4 KB)
Regional level_urban.xlsx (78.2 KB)

Could you support me as soon as possible

Thank you
Reajul
