I get the source data for varied point of sale say one for UK, one for US, one for Germany and so on. But the problem is that for all countries other than US I just have a mobile and full site data (no of visits), For US i have data saying no of visits that happened via IPHONE app, Android app and so on.
So when the point of sale is getting displayed (via list box) in my app I will have something like this
MUK (meaning Mobile UK)
MFR (meaning Mobil France)
MGR(meaning Mobile Germany)
AUS(meaning Android US)
MUS(meaning Mobile US)
When the above options are selected, the formula listed above holds good for all POS other than MUS and AUS.
When AUS is selected the formula should be something like this
