this is the correct expression:
parseDateTime(toString($StartTime ), '_HH_mm') < parseDateTime(toString($EndTime), '_HH_mm')
to complete the task you should use a expression like this:
parseDateTime(toString($StartTime ), 'HH.mm') < parseDateTime(toString($EndTime), 'HH.mm')
let me know if it works :)
Thank you for your quick response. Is it right that I have to create a microflow in which I process this expresssion?
My idea is that when a user presses "Save", there will be a validation that starttime is before eindttime.
Thank you so much, it seems I didn't link to the right variable. I managed to fill in the expression without getting an error, however when I try it out, Mendix says “An error occured, please contact your administrator”.
I thought this happened because I use a 10:15 notation instead of 10.15, so I changed HH.mm in the expression to HH:mm. This didn't work. After that I tried to change the 9:15 enumeration to 09:15, but this also didn't have any effect.
Any other ideas? :)
