Queries not returning data

[Verso]

Good morning,

I am fairly new to Access and have just started to create a database to be used by my local dart league for administration of fixtures and results.

I have built some tables and queries yet the queries do not return any data.

Please could someone have a little look and advise where I have gone wrong?

I think the data in tblPlayers may be corrupt but I'm not sure where or how.........
