change plus/minus inside a sumproduct function

[orang]

=SUMPRODUCT((YEAR(A2:A351)>=2000)*(J2:J351<-0,4)*(H2:H351>J2:J351)*(H2:H351-J2:J351))

A2:A351--------------- H2:H351------J2:J351
18.sept.06------------- -0,6 ------ -2
15.okt.05-------------- 2 ------ -1
10.okt.05-------------- -0,4 ------ -2
08.okt.05-------------- -0,1 ------ -0,5
06.apr.04-------------- 3 ------ -3
03.apr.02-------------- -1,5 ------ -2

now this formula doesnt count like i want.
this forumla checks if the year is > 2000 and if the number in j < -0,4 and if the number in h > j. If it is like this i want to get the result.
BUt in this case there occurs a problem.
18.sept should be = 1,4
15okt. = 3
10 Okt =1,6
08okt = 0,4
06 okt =6
3 apr =0,5
This problem occurs because of the leading sign and i dont know how to elimate this.

How about a spare (helper) column (or two) that has something like =If(H1<0,H1*-1,H1) and use that in your SumProduct, . . or, if the formula in H1 could set itsself positive ?
