Combining lists with seperator

Hey,

I’ve got two lists with values from filtered elements. What I’m trying to do is place the values from list 1 after the values of list 0 in the same order they’re in (in this example, from 0 to 3). However, the number of elements, like parameter values, can vary from project to project. Can someone assist me with this?

I think I found the correct way to address this issue. By utilizing the flatten node and using string.concat on the combine node, I achieved the desired result. For anyone else encountering this problem, I’ve attached a screenshot.

I think it can be achieved as simple as this command is: a+b, if everything is string
