Power Platform Community Forum Thread Details

Dear powerapp community,

I work on HR and i'm responsible to follow up the new employees.

I thought of a menu to quickly plan the training weeks in my calendar.

I have a combobox with a couple of mail adresses, of me and my colleages.

I also have a datepicker to choose the start of the work week.

I can not seem to figure out what i have to do with the following formula and error.

The formula:

Set(
    _myCalendarName;
    LookUp(
        Office365Outlook.CalendarGetTables().value;
        DisplayName = "Agenda"
    ).Name
);;
Office365Outlook.V4CalendarPostItem(
    _myCalendarName;
    "Opleidingsweek 1 - " & Name2_9.Text & " - " & DataCardValue6.Selected.Value;
    DateTimeValue(ConvertStartDate.Text);
    DateTimeValue(ConvertEndDate.Text);
    "(UTC+01:00) Brussels, Copenhagen, Madrid, Paris";
    {
        isAllDay: true;
        requiredAttendees: VerantwoordelijkeOpvolging.Selected.Value
    }
)
 
 
 
 
Info about the formula
Agenda = Dutch voor Calendar
Opleidingsweek = Dutch voor trainingweek
Datepicker is called = SelectedStartDate
I have a label called ConvertStartDate, this converts the startdate to text = Text(SelectedStartDate.SelectedDate)
The Convertenddate has the following: 
Text(
    DateAdd(
        DateValue(ConvertStartDate_1.Text); 
        4; 
        TimeUnit.Days
    ); 
    "dd-mm-yyyy"; 
    "nl-NL"
)
 
The error i get:
 
 
Can somebody point me out what i am doing wrong?
 
Thank you in advance!
 
Greetings Miguel
