Nested Loop Error

I am trying to run two loops inside one another… Getting the following error. Can somebody help me please?

Hi @laymelek , Welcome to the KNIME community.

If you are wanting to nest one loop inside the other, so that the inner loop iterates fully for every iteration of the outer loop, you’ll need to attach it inside your loop with an additional flow variable connection like this:

That way it will become part of the same flow variable stack, rather than creating a new flow stack as it is currently.
