I'm trying to make a dropdown that shows the contacts linked to an account selected in a combobox. This should be easy to do, but I'm unable to make a filter that returns any value.
It seem to me the filter should be something like:
filter(contact, contact.parentcustomerid = combobox.account.accountid)
However Power Apps forces me to use my local language (Dutch) so I can't use the actual entity and field names. The actual filter turn out like this:
Filter(Contactpersonen, Contactpersonen.Bedrijfsnaam = KlantenComboBox.Selected.Account)
However, this doesn't work. Mousing "Bedrijfsnaam" (see screenshot), which I thought would be parentcustomerid, shows _parentcustomerid_value with data type table. Doing the same on Account shows GUID. Mousing over the = shows "invalid argument type".
