Sometimes it’s easy to accidentally add spaces, punctuation or other characters to the name of a calculation. This can cause confusion – are ‘Revenue’ and ‘Revenue ‘ different things?

Openbox will warn you about names that are similar in this way, and ask if you want to merge the calculations or remove one of them. You don’t have to – and sometimes, if you have just added say a % to a name, you want both  – but it can be confusing to leave them both in the model.

Openbox will also warn you if somehow there are two items with exactly the same name. It is designed to prevent this from happening, but as a fallback, it does check for duplicate names and warn before building.

You need to change the name of any duplicates before the model will build correctly.
