I'm afraid not much to go on. Posting on behalf of a user who says he's using PI Datalink in Excel. This message suggests he's using PI Builder instead of PI Datalink. Am I right? Doe3s anyone know what this error means?
Seems this has been asked and answered before:
The type initializer for 'OSIsoft.PIDataLink.AFData.Functions' threw an exception
Many thanks for the info. I can work with that.
