I don't know what you mean by confirmation page. If you want it so they have to first be told something like "You are trying to delete xxx from the database, are you sure you want to?" then you should have another do=whatever in your page to do that.
Also, this makes no sense:
PHP Code:
WHERE leagueid = 1 = $leagueid
And, I still don't know what you think you are doing here:
PHP Code:
SELECT * FROM `denver_results` WHERE 1
