Unable to appender column

Hi team

i am unable to append column tried few things however still getting error.

error— WARN Column Filter 3:37 Unable to merge flow object stacks: Conflicting FlowObjects: <Loop Context (Head 3:34, Tail unassigned)> - iteration 0 vs. <Loop Context (Head 3:63, Tail unassigned)> - iteration 0 (loops/scopes not properly nested?)

Hi @Hammy

When you have 2x Loop Start, you need 2x Loop End (and I see there is only 1).

gr. Hans

so instead of 1x loop start can i use other node as in.

suppose i have 2 column, column A and column A1
and now i want to find these column in 2 different nodes and i want to append the output.

you could use column list loop start to iterate over each column individually
