Button issue

[ioannagr]

Hello everyone, hope you are doing well! 🎄

I have downloaded the QS Variable extension so as to use the buttons. 

This doesn't seem to work for me, and I would like your precious input.

So, I have created a variable called vIssueDate.

I chose fixed values and to the alternative values I added the expressions: max(IssueDate) and max(IssueDate)-1 .

To the KPIs, I edited my expressions like this : =Sum({(<(Product={'blah'}<+<Availability={'yes'}>)*(<IssueDate={$(#vIssueDate)}>)} bags)

I could use some help... 😞
