Use Case "Error Message"
A typical use case for custom parameters with multiple values is the tracking of error messages.
There are different methods available, depending on the technical setup. One scenario is:
- A user is on a page that includes a form. He fills it out and submits it.
- The page reloads and shows multiple errors. A customer page parameter tracks all error messages.
Setting up parameters
When configuring custom parameters (Mapp Q3 > Custom Parameters), you can set the number of parameter values. By doing so, you determine if you want to submit single information or multiple information at the same time. Select "Several values" to create a parameter with multiple values.
