Multiple Set Intersections & Unions

[#1]

Hello Community,

I am in need of set analysis advice.

I am using multiple set selections to find their intersections and add them together (ie. {<...>*<...>+<...>*<...>}). This worked just fine for me up until now. I've isolated the issue to a "prior date" selection that I'm adding to my set. It's purpose is to enable me to compare two timeframes. When I leave the prior date selection out, the set analysis returns what I want it to but when added in, it zeros out the results.

Here is an example of the code that I'm working with:

1. This works!

sum({1

<[Client]=P()>*<[Client]={"NV*","*W"}>

+

<[Client]=P()>*<[Client]={"STR*"}-{"*W"},[Flag]={1}>

} [Count Net])

2. This doesn't.

sum({1

<[Client]=P(),[Submit Dt]={">=$(vPastStartDt)<=$(vPastEndDt)"}>*<[Client]={"NV*","*W"}>

+

<[Client]=P(),[Submit Dt]={">=$(vPastStartDt)<=$(vPastEndDt)"}>*<[Client]={"STR*"}-{"*W"},[Flag]={1}>

} [Count Net])

I've been struggling with this issue for a few weeks now and am really open to any suggestions.

Thank you in advance for your help and insight!
