[Forums] Addind content to the string in a loop w/o overwriting

Hi there again Outsystems community.

I'm struggling here with something that should be pretty basic (and I can actually implement very easily in any other language)

I have a loop which verifies something and if that happens happens, it will add text to a variable.
My main problem is that the string gets overwritted by the latest loop run (obviously), and I would like to add text to it and not overwrite.

For example in any other language it could be very easily done on the expressions by adding + at the end and beginning of each expression, in Outsystem it don't work, but I'm guessing it should be pretty simple.

Here some images to let you understand the context.
