If you read this error, you can see that ,[*empty-string*]

But the select list item need a number for index. You put an empty string there.
Show your block.

blocks of next screen

When you get that Error.
As Soon as the Screen initialize ( what i think )
Or when you click CardView

Can you try this -

Instead of passing loop_number to index of select list item to set Dynamic Label Text,
In procedure pass two more inputs title and subtitle which is required to make list and use them.

which blocks i need to add.
please clarify
