Filtering Data with a value from a Dropdown list

[andreas3]

Hey there,
I’m new to developing app’s but so far I’m fine.
I set up an simple app that should show entries of a mySQL DB and these should be filtered by a value from a dropdown list.
The db ist connected an I set up queries.
One is for the dropdown list, this is working.

Another one, just for test purposes, to show the full entries of the table I want to filter, this is working as well.
And I set up another query with a Parameter for the value “Land” select * from cspeed.speed_all where Land = "$1" Limit 10

Now my goal is to get the selected value from the dropdown list into the parameter from the second query
Conf of dropdown:

Conf of repeating Group

Thanks for helping me
Best regards
Andreas

I have found a different solution. I loaded the complete Data in the RG an the use the Dropdown as a Filter Option.
But anyway if somebody has an idea to my first question I will be happy to hear.
Thank you
