Using set analysis to reference the value of another field

[paulm]

Hi,

I know I am missing something silly here but I can't see how to do it! 

Basically I have two dates, one is a demension and the other I want to do a sum of values but to limit it to the date equal within the demension minus 1 day.  I was wanting to do it via set analysis but I am unsure how to reference it.

Any help would be great.

Thanks

Paul
