Having a ton of trouble with this index/match/sumif formula

Hi all,

I am trying to create a formula that will tally the following cells containing text based on the following criteria.
- Date (or range of dates)
- Shop
- Position

I've been trying to use a SUMIF/COUNTIF with an index/match but i can't seem to get it to work.

I've attached a sample of the sheet.

Any help is appreciated.
Thanks
