Hi @111207

The Panel Error you are seeing is because the Bucket Script is transforming "Sum of Duration" into the boolean result of "Sum of Duration \< 1". It's transforming the value, not filtering out the value. Hope that helps.

Hi coery.robertson

OK I'm understand. The result params.a \< 1 It's tranforming the value.

I need to create with this step

1.Sum of Duration  
2.Filter Sum of Duration \< 1  
3.Cardinality of Card ID if Sum of Duration \< 1

Please Guide me how to do that. Because I'm select group by \> Filter .It can't to select field Sum of Duration

Thank you so much
