Not all statements are permitted in the Immediate window. This error has the following causes and solutions:
A declarative statement was used. For example, Const, Declare, Deftype, Dim, Function, Option Base, Option Explicit, Option Compare, Option Private, Private, Public, property procedure declaration statements (Property Let, Property Set, and Property Get), ReDim, Static, Sub, and Type are not allowed in the Immediate window.
Remove the declarative statements from the Immediate window.
A control flow statement was used, for example, Sub, Function, Property, GoSub, GoTo, Return, and Resume.
Remove these statements from the Immediate window.
There is no logical connection made between separated physical lines in the Immediate window, so statements formatted as multiple physical lines, such as a block If statement, can't be properly executed.
Such blocks can be typed on a single physical line, with each statement separated from the next by a colon (:). Conversely, you can extend a single statement across physical lines in the Immediate window by using the line-continuation character, which is a space followed by an underscore ( _).
You tried to execute some code in the Immediate window that invalidates the current state of your program and requires you to reinitialize the program.
Remove the code in question from the Immediate window.
