I know error 450 is associated with the Style name not existing

On Error Resume Next
Err.Raise 450
Debug.Print Err.Description

"Wrong number of arguments or invalid property assignment"

Could be many reasons apart from a Style not existing, not that I have any
idea what might be the reason.

Difficult to hazard a guess just looking at your code. If you can, upload a
non sensitive file to show the error.
