Invalid use of object
You tried to use an object in an incorrect way. This error has the following causes and solutions:
You tried to discontinue an object reference by assigning Nothing to it but omitted the Set keyword:
MyObject = Nothing
Use the Set statement to set an object to Nothing. Assuming MyObject is an object, you must set it to Nothing with the Set statement:
Set MyObject = Nothing
Omitting the Set keyword is an implicit use of Let, which causes an attempt to perform a value assignment, rather than a reference assignment. Nothing can't be used in a value assignment.
You attempted to use Nothing in an expression.
Rewrite the expression without the Nothing.
