I installed the Celedon auto number plugin (as recommended on other threads in the blog) so i can create an opportunity reference for new opportunities on my system, the plugin installed without any problems and i can see it where i need it.
Can anyone explain how i create a new filed to add to the opportunity field though?
I have tried clicking on new and creating a new auto number but every time i add an entity name it says the entity does not exist (see screenshot).
Would appreciate any help on this.
Thanks,
Stephen
