    Hi,
     
    You can use xml & xpath functions to achieve this.
     
    Firstly, in array variable you need to store the object instead of plain text as shown below:
    {
    "uniqueid": "<dynamic id value>-<dynamic title value>"
    }
     
    Before select action, add compose action to convert variable in xml format. Use below expression to convert to xml. Expression needs to be entered in the 'Function' window:
    xml(json(concat('{"root":{"items":',variables('NetworksIdTitle'),'}}')))
     
    Finally, to get the title from array variable based on the id use xpath function. Enter the below expression in title map property value to get the required value:
    last(split(xpath(outputs('Compose'), concat('string(//uniqueid[starts-with(text(),"',item()?['ID'],'")]/text())')),'-'))
     
     
     
     
    OUTPUT:
     
     
     
     
    If this helps & solves your problem, please remember to like and accept my solution as it will help others in the future.
