Better, instead of zipping the project folder into a zip archive, use project export. In the Projects menu - right button on your project - Export. You will get a single file of minimum size with the *.rbase extension. Note: attached files are not placed into archive. In the same place in the Projects menu, you can import the project.
In the "Routes" object, delete the "Condition" condition field, and in the "Vertrek" field, delete the "Copy from" property.
Variant of the formula for the "Route" composite field:
[Vertrek.Pleknaam] - [Via #1.Pleknaam] - [Via #2.Pleknaam] - [Via #3.Pleknaam] - [Aankomst.Pleknaam]
But in order not to write extra "-", add the String functions to check the values of the fields: if they are empty, then nothing is displayed, otherwise, "-" is displayed:
[Vertrek.Pleknaam][String(Via #1.Pleknaam=?: - )][Via #1.Pleknaam][String(Via #2.Pleknaam=?: - )][Via #2.Pleknaam][String( Via #3.Pleknaam=?: - )][Via #3.Pleknaam] - [Aankomst.Pleknaam]
To update existing records, use the Apply button in the Composite field properties in the Constructor.
