Problems with displaying Time from dropdowns



I created some dropdowns for choosing a time. The initial idea was to calculate the difference between END & Start time, which would then give a precise time.

The dropdowns look like this:

So we have 4 dropdowns in total: (from left to right) "HourValueStart", "MinuteValueStart", "HourValueEnd", "MinuteValueEnd"

I tried following code first:


    Value(HourValueEnd.Selected.Value) - Value(HourValueStart.Selected.Value);
    Value(MinuteValueEnd.Selected.Value) - Value(MinuteValueStart.Selected.Value);


but once I want to submit this, it returns an error saying "Invalid value '1619823600000' for field 'Einsatzzeit', expected a string".


Then I tried something else:


HourValueStart.Selected.Value & ":" & MinuteValueStart.Selected.Value & " - " & HourValueEnd.Selected.Value & ":" & MinuteValueEnd.Selected.Value 


with the goal to display exactly what was given as input. In this case it would have been "06:00 - 07:00". When I submit and go to check, it is just blank. In the spreadsheet (where it is stored once we hit the submit button) the column "Einsatzzeit" is also blank.

Anyone an idea what the issue could be?


@Anonymous ,

Date/Time fields are either Date only or Date/time (not time only). The date is actually stored with a time of 00:00.

Are you using Excel here? If so, you might want to watch this video.

Hi @WarrenBelz ,

yes I am using Excel, because it was a requirement. Thanks for the video!

I got around this, by using normal Text instead of Date, to display the time.
