Delete Records Button Disabled

[stephen81]

I have a database with a continuous form listing my records. Unfortunately I seem to be unable to delete records from within this form even though 'Allow Deletions' is set to 'Yes'. The delete record button on the toolbar is greyed out and if I select a record and hit the delete key, I get a message in the status bar saying 'Records not deleted. Data is read-only'.

Does anyone have any idea why this might be?

The forms underlying query is un-editable

What makes a query un-editable? It's only a select query. I thought it could be because it also had a field from a linked table in but I took that out and it still won't let me delete.
