Leap Year Dates Causing Error When You Pull Dates For Non Leap Year

I'm trying to generate this query, that displays Budget Current Year , Actual Current Year and Prior Year Revenue. When It comes to the Budget and Actual everything works fine, however when I try to add the query for the Prior Year I get an error, and I realized that the leap date is causing the error


Here is what I'm trying to generate






InnCodeID
Quarterly
Monthly
Days
Period
Year
BARmRev
AARmRev
PYRmRev

Here is the error that I'm getting:

The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.

Here is my Transact-SQL Syntax (summarized because I Couldn't post it):

SELECT

(CASE WHEN (CASE WHEN dbo.Trans.Tr_Dept = '10' AND dbo.Trans.TR_Main = '5120' AND dbo.Trans.tR_sub = '01'

AND Year(dbo.Trans.TR_Date) = Year(dbo.CurrentDate.CurrDate) AND dbo.trans.Datatype = '1'

THEN dbo.trans.Tr_Amount ELSE NULL END) IS NOT NULL THEN

(SELECT Trans1.TR_Amount

FROM dbo.Trans Trans1

WHERE Trans1.TR_Dept = '10' AND TR_Main = '5120' AND TR_Sub = '01' AND trans1.TR_Date = CAST((CAST(Month(dbo.Trans.TR_Date)

I appreciate all your help
