Nested Aggregation & Cumulation

[#1]

I have a dataset with two dimensions and one simple expression (count).

I need to add an expression that is the total of the counts within one of the dimensions. So this is what I have, with Aggregate1 defined as

Aggr(count(ID),Payband)

Payband	Minimum Bands	Count1	Aggregate1
< 1.5	400000	44	44
1.5 - 2	400000	53	3215
1.5 - 2	500000	1451	-
1.5 - 2	600000	902	-
1.5 - 2	750000	470	-
1.5 - 2	1000000	288	-
1.5 - 2	1500000	51	-

What I need is two things. I need the 3215 to show for all of Payband, but then I also need to show the cumulative distribution as follows:

1.5 - 2	400000	53	3215	98%
1.5 - 2	500000	1451	3215	53%
1.5 - 2	600000	902	3215	25%
1.5 - 2	750000	470	3215	11%
1.5 - 2	1000000	288	3215	2%
1.5 - 2	1500000	51	3215	0%

Please please please can you let me know how to calculate these as expressions in qlikview.

Thanks,

Joe
