Perspective table selection

I used a table component in Perspective , when I selected one row in the table , I do have data in props–>selection–>data, but when I try to put the data to a text of label, it is empty list …very very annoying question, may I get some help here?

Thank you

can you post a screenshot of your binding to the label?

Thank you for your response , I knew what issue caused and fixed , but still, thank you for your response:)
