Hi Experts,

I do have value for stTRGT and line 4 - shftTRGT is 'NULL' (correct value). While in line 5 while trying to sum, i do get NULL instead of value of stTRGT.  
Please do advice.

	SET stTRGT = timeOUT / 3.5;
	SET shftTRGT =(select sum(sec) from workinghrs where endTM <= timeIN);
	SET shftTRGT = shftTRGT + stTRGT;

By default concatenating with a null in tsql results in a null, you need to use COALESCE :

SET shftTRGT = COALESCE(shftTRGT, ' ') + stTRGT;
