I have a page where a customer can make amendments to their product which changes the price. I have a data element changed rule that fires on change of the price and saves it to an eVar.
When I review the values for the eVar in my report I have many more values than I do customers. It looks like rather than overwriting the value of the eVar with the new value, it's saving every value.
Is this expected behaviour or do I need to do something different either in the configuration of the eVar or my DTM rule firing on the page?
Any value which will be assigned to an eVar will be saved and shown in the reports as well. This is an expected behavior.
