Concatenating Arrays

Hello,

I am trying to concatenate and post values from 2 arrays (Category and Note) into a list

Looking into posting it similar to this:
Default - Default
Covid-19 Hardship - Please forward all new info to
Suspicious Activity - Please forward all new info to
…etc

I am able to post just straight info by putting Category and Note into one field but it just returns as one long text vs being separated via newline.

I also tried creating a new variable by putting the arrays together (merge_data) and joining them using join(merge_data;newline) with no success.

Any ideas?

Well you can Iterate on one array and then using its bundle order position value you can get value of second array and simply combine them , that will give you a final string and then split it again to have a new array ,
