Need Help in Weighted average in Qlikview

[QGuy]

Hello I'm new to Qlik, I have a table like this 

Invoice	Amount	Days Taken to Invoice
123	50,000.00	45
456	100,000.00	4
789	250,000.00	2
234	15,000.00	30
567	25,000.00	2
987	250,000.00	10

In the table I have to calculate a running weighted average on the average dayes it takes to invoice. example 

total invoice (sum of Amount column) and the weighted average days it takes to invoice.

Any help wiill be appreciated

Hi,

This is the community related to Reporting Services. I suggest you move this post to the community of QlikView https://community.qlik.com/t5/QlikView-App-Dev/bd-p/qlikview-app-development to have more possibility to get an answer.

Better if you search your question in that community before posting: it could be already solved in old conversations.

Best Regards,
