Spreadsheet A has the phone number in one cell formatted like:

(123) 456-7890

Spreadsheet B has the phone number separated in three separate columns like:

123 456 7890

I used the CONCANTENATE function to string the text together, but if the
phone number has a 0 starting the group it isn't showing up in my new cell.
What am I doing wrong? See below:
