first problem: your set statements aren't correct

you either need to do:

SELECT  @TILL_TOP_O_HR_DATE = (60-RIGHT(convert(varchar(5),getdate(),114),2)),

or

SET  @TILL_TOP_O_HR_DATE = (60-RIGHT(convert(varchar(5),getdate(),114),2)),

second problem: you have some lines where you're trying to set variable values without using SET or SELECT (see line 54)

third problem: you seem to be trying to re-declare variable names that you've already used previously in the UDF

the code obviously needs major cleanup, but at the very least, this should allow you to create your UDF - all i did was fix a bunch of syntactical errors and didn't look at the logic of it though
