I'm trying to create a summary sheet with a table that returns the same cell in each sheet. My sheets are called: June 2016, July 2016, etc

I have created a table where names of the sheet start in C2, A3 is the cell on each sheet I want to return and my formula is currently: =INDIRECT("'" & C2 & "'!A3"). However when I use this formula, I get a 0 for all the sheets. I have tried with other cells that definitely contain values but it returns 0 each time. Any idea/fixes for this? Thanks!

A......B...........C.................D........... E.....F

2 ................June 2016.....July 2016
