Nested gallery filters with dependent logic

Hi everyone,

 

I am trying to build a basic printable calendar for a non-profit disability support organisation. Their rostering system can't output printable rosters in a format which is understandable to people with intellectual disabilities so I am trying to build something. Their rostering system spits-out a couple of CSV reports which can be copy-pasted into a SharePoint list then manipulated by PowerApps.

 

Once of the lists contains a list of events, each having a "date of first event" as well as various frequencies (ie once, weekly, fortnightly, monthly, etc).

In PowerApps, the printable calendar has 'squares' for each day which are a gallery and should display a list of events for that day (so there will be 28 galleries in a calendar layout). There is a single date picker at the top of the screen which sets the first Monday of the month to print.

I am having trouble with the logic for each square (gallery). 

I want it to show the following:

If the frequency of the event is "Once", event start date = datepicker (or datepicker+1, datepicker+2, etc)

If the frequency is "Weekly", event start date = datepicker OR Weekday(event start date) = Weekday(datepicker)

then Fortnightly If event start date = datepicker OR event start date = day of week && datediff(calendardate to event start date ) / 14 = x.0 (whole number)

If the frequency is "Monthly",event start date = datepicker OR Event start date (day only) = datepicker (day only) - i.e. 26th

If the frequency is "Annually", event start date = datepicker OR Event start date (day&month only) = calendardate (date&month only) - i.e. 26th May

 

I hope the goal makes sense?

This is the code so far (be kind):

//show only events for selected roster name
Filter(RosterEvents,ParticipantRosterName = ComboBox1.Selected.Result,

//also show one-off events on this tile's date
EventFrequency = "Once"&&
Text(DateTimeValue(Text(DatePicker1.SelectedDate+1)), "[$-en-US]dd/mm/yyyy") = Text(DateTimeValue(Text(EventStartDate)), "[$-en-US]dd/mm/yyyy")
||

//also show weekly events falling on this day of the week
EventFrequency = "Weekly" &&
Text(DateTimeValue(Text(DatePicker1.SelectedDate+1)), "[$-en-US]dd/mm/yyyy") = Text(DateTimeValue(Text(EventStartDate)), "[$-en-US]dd/mm/yyyy") ||
Weekday(DateTimeValue(Text(EventStartDate))) = Weekday(DateTimeValue(Text(DatePicker1.SelectedDate+1)))

//also show events falling on this day of the fortnight

//also show events falling on this day of the month

//also show events falling on this day of the year
)

 

Having the logic in this order doesn't work, it obviously just evaluates everything. 

Can anyone give me some pointers on how to order/layout the logic to acheive this?

 

Any help is very much appreciated and will help many people living with a disability.
