Current vs Previous term - Urgent help if possible!!

[QlikBeginner1]

Hello.

I am creating a dashboard, and one of the features I want to implement is to have a page where it shows the total GWP for the Max Policy and the previous Policy, and to have the comparison.

Sum({<PolicyEffectiveDateCh = {"$(=Max(PolicyEffectiveDateCh))"}>} GrossWrittenPremium) - I currently am using this expression which calculates what I want, but only when I select a certain Policy. When I have not made a selection, the sum is not correct.

Sum({<PolicyEffectiveDateCh = {"$(=Max(PolicyEffectiveDateCh)-1)"}>} GrossWrittenPremium) - When I try this - I wanted to select the Max Policy Effective Date -1 to select the record before the Max record, however the output comes as 0, when I select a certain policy or when I have no selections?

Once I have these calculations, I am able to do the comparison between the two. Can anyone help me do a total GWP for each Max record of PolicyNumber? and then the prior record GWP?

Thanks
