MySQL - SQL Database Connector parameters issues

Hi there, I have an issue with this pluggin.
I wanna show info with a dynamic parameter.
I put an example directly and works fine, also the repeating group give me the correct info

but if I change the value to a parameter, the scenario doesn’t work. The return always is empty even if the id number is the same

Anyone can help me with that? Is the pluggin working?

If you still fight with it, try write this

WHERE cadete_id = ?
WHERE cadete_id = ‘$1’

EDIT: in me that work - and that portugal guy do this same at this movie

I explained this in more detail here: SQL Connector SQL Server Parameter Format - #2 by ben13
