How do I concatenate array with value of string variable in Power Apps

1 I initialize one string variable Product_line
2 Assign this variable to items from List folder in SharePoint (name of spreadsheet)

3 Made loop apply to each line by line from excel file
if you look in the Flow I create one Array that is going to increment

4 I creating a csv file where I need to concatenate the variable from second step + content of the Array on previous step

 I need to know from which file each line is coming from

My preferred way to concatenate text strings in Power Apps is by using the new $-String syntax. To do this we put a dollar sign ($) in front the text string's quotation marks and use curly braces {} to denote the parts of it which are expressions – functions, formulas or variables that might change.
