Hi @Chumairoh_Rumani
We're glad you're here. When you get a chance, please introduce yourself on this forum thread.

You have three bugs in your form:

  • two in calculations where you have something like int((today()-${tanggal_lahir_ibu}) div 365.25,0) and int((today()-${tanggal_lahir_balita}) div 365.25,0). You should remove that ,0 I don't understand why you added it there.
  • the last one is in the settings sheet in instance_name (concat(${status_responden},'-'${nama_balita})) where you missed a comma after '-'
