Problem Returning A Declared Variable

when I run this sproc all I get out of it is "the commands completed successfully" and doesn't return the value. If anyone can point out where the error is I would really appreciate it. Thanks


Code:


Create Procedure LookupLeagueIdByUserName(@userName as varchar(40) = '') as
begin
if (@userName = '')
raiserror('LookupLeagueIdByUserName: Missing parameters', 16,1)
else
begin
Declare @leagueId int
Set @leagueId = -1

--Check if the username belong to a player
Select @leagueId = leagueId From Users u
inner join players p on p.userId = u.userId
inner join teams t on p.teamId = t.teamId
where u.userName = @userName

if (@leagueId > 0)
begin
return @leagueId
end
else
begin
--Check if the username belong to a teamUser
Select @leagueId = leagueId From Users u
inner join teamUsers tu on tu.userId = u.userId
inner join teams t on tu.teamId = t.teamId
where u.userName = @userName

if (@leagueId > 0)
begin
return @leagueId
end
else
begin
--Check if the username belong to a leagueUser
Select @leagueId = leagueId From Users u
inner join leagueUsers lu on lu.userId = u.userId
where u.userName = @userName

if (@leagueId > 0)
begin
return @leagueId
end
else
begin
--username is not in db or is an admin user
return -1
end
end
end
end
end
return
-- when I run this I get no results returned
LookupLeagueIdByUserName 'chris'
