Store procedure issue

Question

I have error in my store procedure execution time.....

Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 0, current count = 1

My store procedure is

 

ALTER procedure [State](

@stid varchar(15),

@stname varchar(50),

@crdate date,

@Action varchar(15)

)

as

begin

SET NOCOUNT ON

SET XACT_ABORT ON

begin try

begin transaction

if(@Action='INS')

begin

insert into tblState(StId,State,CreatedDate) values (@stid,@stname,@crdate)

end

else if(@Action='ALL')

begin

select * from tblState

end

else if(@Action='UPD')

begin

update tblState set State=@stname where StId=@stid

end

else if(@Action='DEL')

begin

Delete from tblState where StId=@stid

end

else if(@Action='sel')

begin

select * from tblState where StId=@stid

end

else if(@Action='val')

begin

select State from tblState where State=@stname

end

commit

end try

begin catch

IF @@TRANCOUNT > 0

ROLLBACK

end catch

end

Please help me guys..... I am struggle in this error
