Hi,

If you are using a datasource like SQL or Dataverse  you will got a Delegation issue, what you could do is
in your screen there is a OnVisible property,

and pate this code, so you could use variables

UpdateContext({minPopulation: Min('Data Sensus Penduduk',Population)});
UpdateContext({maxPopulation: Max('Data Sensus Penduduk',Population)})

then assign those values minPopulation/maxPopulation to the respectives Min/Max Properties.

regards.

halo thank you for replying to my post. Regarding the data source, i am using Sharepoint List, and i just modified the change you provided but it still has the same error.

Hi,

Try this

UpdateContext({minPopulation: First(Sort('Data Sensus Penduduk',Population,Ascending)).Population});
UpdateContext({maxPopulation: First(Sort('Data Sensus Penduduk',Population,Descending)).Population})

you can also skip the variables if you want and paste it direct in the Min/Max properties

regards.

if it was helpful please consider mark it as answer ✔✔

do i have to put this 

UpdateContext({minPopulation: First(Sort('Data Sensus Penduduk',Population,Ascending)).Population});
UpdateContext({maxPopulation: First(Sort('Data Sensus Penduduk',Population,Descending)).Population})

on my Screen1"OnVisible" too? 
Update: the other delegation issues have gone except for the gallery's, 

and it still wont show anything.

Hi @Deltodeus ,

This is a warning not an error. 

What is the total items amount of your list?

Is there an item that meets this condition ?

If items<=2000, you could modify the setting and refresh the datasource to check it again.

Besides, you could put your cursor at the end of the formula to check the output.

Best Regards,

sorry, UPDATE

the problem was solved, it was due to sharepoint list's format. Before the "Population" column was set to "a single line text". Here the format should be set to "Number".  Thank you very much for the people who have tried to help me with this case 🤗
