I am trying to create a flow which will add my closing dates for my opportunities into my calendar.  I contacted Salesforce support but unfortunately they are not able to help with the error I keep getting....    Below is the error report I get when trying to create an opportunity when this flow is activated.  At the bottom it says required field missing [Activity Date], what is this field?  Any help is appreciated.

I am looking to build a custom app that I can post external sales numbers and share with our team which is separate from our opportunities we are working on.  We are a manufacturers representative and we receive month reports from each manufacturer and I would like to manually plug these numbers into a custom app that would be shared with our team, and have the ability to create charts.  (IE. Sales by province, YTD VS Goal, Etc, etc).  We currenlty share within a excel spread sheet as attached but would like integrate into salesforce.  I am new to Salesforce, so if someone was able to point me in the right direction it would be greatly appreciated.
