Hi @Preeti zade ,
The condition is failing, resulting in a return value of 0.
Kindly check if the country code is stored in uppercase, as case sensitivity might be causing the mismatch. 

Check case sensitivity — ensure the country code in your data and in the filter condition match exactly (e.g., both uppercase using Upper()).

Example fix:

Upper(CountryCode) = Upper(InputCountryCode)

If you want to compare 2 string

use Trim() to remove space first/last and ToUpper/ToLower()
