Sheet #1: Daily Data

Column A: Days in format dd/mm/yyyy
Column B: Quantity

Sheet #2: Quantity by Month

Column A: Months in format mm/yy
Column B: Summed Quantity

I tried using:

```
=SUMIFS('Daily Data'!E17:E600,'Daily Data'!A17:A600,"=??/01/2013")

```

this does not work

tired using:

```
 =SUMIFS('Daily Data'!E17:E600,'Daily Data'!A17:A600,"=??/"&MONTH(A1)&"/2013")

```

nope, doesn't work

Tried if with asterix and it does not work either
