Return more than one match function

Hi everyone,

I`m struggling to return the actual hours associated with the invoice number in sheet 2 to sheet 1. I tried using a match function however it only returns the first instance it finds, whereas I want it to return the actual hours for everytime invoice number(sheet1) = invoice number (sheet 2).

Sheet 1:
column B: invoice number Column J: Actual hours

Sheet 2:

Column C invoice number
column J Actual Hours

Enter the formula below on Row 2 of Sheet1 in whichever column you want the Actual Hours to appear, and copy down to row 26:
=INDEX(sheet2!$J$2:$J$16, MATCH(B2,sheet2!$C$2:$C$16,0))
