issue with VSTACK formula

Good afternoon All,

I have a formula in cell A6 tab "Kitting Schedule" that I can't get to work. It should pull data based on date from cell A2 and by the qty entered into cell B2, but it isn't for reasons that I can't figure out. I have included this file and would appreciate any guidance! There is a password on these sheets- "schedule" without the quotations.

Thank you in advance,

Adam
