Unable to apply custom expressions

I tried applying Percentile but i am unable to view the results.
Can anyone help?

Hi @Bhaumik1
Post "Diagnostic Info" from Admin > Troubleshooting, and which database type you are querying.

@Bhaumik1 I don't know which database you are querying, so have a look at the database logs to see if there's errors. And check Metabase for errors in Admin > Troubleshooting > Logs.
