Node - Red For Loop

Can anyone see what mistake ive made in my for loop code, I want to display the 20 different beacons but at my output instead of getting the list of 20 beacons i am getting the last beacon spread out over 20 different outputs as "B","e","a","c","o","n","_","0","2","undefined","undefined","undefined","undefined","undefined","undefined","undefined","undefined","undefined","undefined","undefined"

Post your flow, we cannot reverse engineer this. Or at least post the function node in code.
I would start by defining namelist as an array: [content], not (content).

thats it that has fixed it i messed up by using the () brackets instead of the for an array thank you
