you are converting it into varchar string format. Please don't to that. remove cast and try it

So are you saying that the first SUM() returns 1281.5 and the second SUM() returns 270 and you want the result of those two SUM() functions put together so that the result it 1281.275?

If so, that does not make sense. That would be equivalent of the following:
1281.005
+0000.270
---------
1281.275

Use IMPROVE QUESTION link above and please explain in more detail.

Your database should not do this. If you want to enforce a certain number of decimals, or whatever, your presentation layer should do this. Your data itself should not be truncated, it should remain the real value.

And yes, your SQL is a nightmare. Get rid of the varchar casts. How can 16 casts to varchar(50) give you a four digit number either side of the decimal ? Also, why on earth are you concatenating empty strings ?
