Hi @ilyak 

Where are you stuck at and what have you tried?

1. Are you able to use LOOPS to extract each item from the collection?
   Collection1 = �“one”, “two”, “three”, ”four”, “five”]
   tmpStr => get item from collection
2. Are you able to concatenate strings and variables?
   Msg1 = Msg1 + tmpStr 

Then you should be able to create the following string Msg1.

one two three four five

Hi @ilyak,

The easiest way to achieve this solution is to use the Join items in collection action.
