Check in the help file for info on the INDIRECT() function

If you put "Week 1" in cell A1, your formula would read

=INDIRECT("'"&a1&"'!B3")

PS - If you change your tab/sheet names so that there are no spaces - Week1
or Week_1, as examples - you can dispense with the single quotes around the
sheet name
