How to calculate growth percentage for any 2 months based on user selection

[BlakeGri2093]

Hi Qlik Experts

I  want to create the sales KPI for growth based on the user selection so they want choose any 2 month and the KPI will return the growth with that selection. For example, if they choose August and January the KPI will return the sales growth between the august and January. Can you guy help me with that problem?

Is this based on a selection of date or Month? May be something like this

Sum({<Month = {"$(=MaxString(Month))"}>} Measure)/Sum({<Month = {"$(=MinString(Month))"}>}Measure) - 1
