Selecting Based On The Value Of A SUM

Okay, let's see if I can explain this one. I am summing multiple lines of data from a labor detail table, by status. Using this query

SELECT EM.Lastname, LD.WBS1, LD.WBS2, P.Longname, SUM(LD.Held) AS HELDLABOR, SUM(LD.TBWRittenOff) as TBWrittenOffLabor, SUM(LD.WrittenOff) AS WRITTENOFFLABOR
FROM PR P INNER JOIN
(SELECT WBS1, WBS2, SUM(CASE WHEN BillStatus = 'h' THEN Billext ELSE 0 END) AS Held, SUM(CASE WHEN BillStatus = 'w' THEN Billext ELSE 0 END) AS TBWrittenOff,
SUM(CASE WHEN BillStatus = 'x' THEN Billext ELSE 0 END) AS WrittenOff
FROM LD
WHERE BillSTatus IN ('x','h', 'w')
GROUP BY WBS1, WBS2) LD ON p.WBS1 = ld.wbs1 AND P.WBS2 = LD.WBS2 INNER JOIN
EM ON p.ProjMgr = EM.Employee
WHERE p.Status IN ('a', 'i') AND P.ChargeType = 'r'
GROUP BY EM.Lastname, LD.WBS1, LD.WBS2, P.Longname
ORDER BY EM.Lastname, LD.WBS1

I get these results...

Okay, so now, of coarse, I want to change everything. I only want to return rows if there is a value > 0 in either Held Labor or TBWrittenOffLabor. Otherwise, no row return.

Here's what I tried, but it didn't work out because it still returns rows, it just zero's out the values for written off labor.

SELECT EM.Lastname, LD.WBS1, LD.WBS2, P.Longname, SUM(LD.Held) AS HELDLABOR, SUM(LD.TBWRittenOff) as TBWrittenOffLabor,
SUM(CASE WHEN LD.HELD > '0' THEN LD.WrittenOff ELSE '0' END) AS WRITTENOFFLABOR
FROM PR P INNER JOIN
(SELECT WBS1, WBS2, SUM(CASE WHEN BillStatus = 'h' THEN Billext ELSE 0 END) AS Held, SUM(CASE WHEN BillStatus = 'w' THEN Billext ELSE 0 END) AS TBWrittenOff,
SUM(CASE WHEN BillStatus = 'x' THEN Billext ELSE 0 END) AS WrittenOff
FROM LD
WHERE BillSTatus IN ('x','h', 'w')
GROUP BY WBS1, WBS2) LD ON p.WBS1 = ld.wbs1 AND P.WBS2 = LD.WBS2 INNER JOIN
EM ON p.ProjMgr = EM.Employee
WHERE p.Status IN ('a', 'i') AND P.ChargeType = 'r'
GROUP BY EM.Lastname, LD.WBS1, LD.WBS2, P.Longname
ORDER BY EM.Lastname, LD.WBS1
