Hi; Let me jump in the immediate use case here.

I have a list of channels to select from in low code apps; I have a feed which shows me the multicast

feedA: 239.1.1.11:1234

The expected parameter input is: udp://239.1.1.11:1234

how do I combine a set string with a feed in the low code apps option?

I was hoping to do something as "userdefinableText"+"FeedValue"

but I do not seem to be able to combine items; or is there another option somehwere?

Use case: select stb; press the "select TV channel" button

select channel and press Retune STB.
