Object variable or With block variable not set (Error 91)
See Also Specifics
There are two steps to creating an object variable. First you must declare the object variable. Then you must assign a valid reference to the object variable using the Set statement. Similarly, a With...End With block must be initialized by executing the With statement entry point. This error has the following causes and solutions:
You attempted to use an object variable that isn't yet referencing a valid object.
Specify or respecify a reference for the object variable. For example, if the Set statement is omitted in the following code, an error would be generated on the reference to
Dim MyObject As Object ' Create object variable. Set MyObject = Sheets(1) ' Create valid object reference. MyCount = MyObject.Count ' Assign Count value to MyCount.
You attempted to use an object variable that has been set to Nothing.
Set MyObject = Nothing ' Release the object. MyCount = MyObject.Count ' Make a reference to a released object.
Respecify a reference for the object variable. For example, use a new Set statement to set a new reference to the object.
The object is a valid object, but it wasn't set because the object library in which it is described hasn't been selected in the References dialog box.
Select the object library in the Add References dialog box.
The target of a GoTo statement is inside a With block.
Don't jump into a With block. Make sure the block is initialized by executing the With statement entry point.
You specified a line inside a With block when you chose the Set Next Statement command.
The With block must be initialized by executing the With statement.
