i. Runtime Error 91 is a Visual Basic error which means "Object variable not set". This indicates that the object was never created using the "Set" command before being used.

Here are some possible causes of Runtime Error 91:

* The object variable was never created using the "Set" command.
* The object variable was created, but the object it refers to was destroyed before it was used.
* The object variable was created, but the object it refers to is not accessible.
* The object variable was created, but the object it refers to is not in a valid state.

Here are some possible solutions to Runtime Error 91:

* Make sure that the object variable is created using the "Set" command before it is used.
* Make sure that the object variable is not destroyed before it is used.
* Make sure that the object variable is accessible.
* Make sure that the object variable is in a valid state.

Here are some additional tips for avoiding Runtime Error 91:

* Use the "Option Explicit" statement at the top of your code to force yourself to declare all object variables.
* Use the "With" statement to avoid having to repeatedly set the reference to an object.
* Use the "On Error GoTo" statement to handle errors gracefully.

If you are still getting Runtime Error 91 after trying the above solutions, you may need to consult a Visual Basic expert for help.

ii. Runtime Error 91 in Excel/Word is a Visual Basic error which means "Object variable not set". This indicates that the object was never created using the "Set" command before being used.

For example, if you have a variable called "mySheet" and you try to use it to refer to a worksheet without first creating it, you will get Runtime Error 91.

To fix Runtime Error 91, make sure that you create all object variables using the "Set" command before you use them. For example:

```
Dim mySheet As Worksheet
Set mySheet = Sheets("Sheet1")
```

This will create a new object variable called "mySheet" and assign it a reference to the worksheet named "Sheet1". You can then use the "mySheet" variable to refer to the worksheet in your code.

Here are some other tips for avoiding Runtime Error 91:

* Use the "Option Explicit" statement at the top of your code to force yourself to declare all object variables.
* Use the "With" statement to avoid having to repeatedly set the reference to an object.
* Use the "On Error GoTo" statement to handle errors gracefully.
