Changing format to time of hh:mm:ss v hh:m:s

[YcnanPowerBI]

Hello - I have the below DAX to sum up a talk time column, but I would like to is to display in hh:mm:ss.  The screenshot below shows how it shows up on my report where it may show 1 or 2 digits for minutes or seconds depending on total.  Any way to change this to hh:mm:ss?  Thanks in advance for any help here!

1 Inbound Total Talk Time = var _sum = sum(Append1[Inbound Talk Time])

VAR hours =  INT( _sum * 24 )

VAR Minutes = MINUTE(_sum)

VAR Seconds = SECOND(_sum)

RETURN

Hours & ":" & Minutes & ":" & Seconds

I found the solution!  Changed the last segment to 

FORMAT(Hours, "00") & ":" & FORMAT(Minutes, "00") & ":" & FORMAT(Seconds, "00")
