How to remove the coma between string text fields concatenation

[Aarón Palazón Barber]

Hello all! I have a problem with a concatenation of various texts fields. In my automation I collect all the content that are in a custom field (strings) from all epics and put all the information into a parent custom field. The issue I have is that the content of the different epics is separated by comas in the parent as shown in the image: 

Anyone can help me to remove this comas? In the automation I have this smart value to fill the parent Impact field: 

"{{lookupIssues.Impact.concat("\n")}}"

Hi @Aarón Palazón Barber  For this you can do one thing :

1. Add an Action >> Create variable >> give name like "ImpactData" and put smartvalue : {{lookupIssues.Impact.concat("\n")}}, it store above screenshot data. 

2. Then put Edit Action and update Impact field in Parent with smartvalue : 

{{ImpactData.remove(",")}} >> ImpactData is variable name.

This should remove comma.

Thanks
