Dim X As Integer 'Declare X as type Integer
X = 10 'Assign X the numeric value 10
If X = 10 Then 'If X is equal to 10
MessageBox "X is equal to 10" 'Tell the user X is equal to 10
Else 'Otherwise, if X is not equal to 10, (Which
'cannot happen here)
MessageBox "X is not equal to 10" 'Tell the user X is not equal to 10
End If 'End of IF loop

The following example checks to see if the value entered into an inputbox is numeric. (The function IsNumeric tests a value to see if it is numeric. If it is numeric, it returns a value of True. If it is not numeric, it returns a value of False.) If the value is not numeric, an error message is displayed.

'Declare X as type Variant

X = InputBox("What is your age?")

'Ask for the user's age

'Tell the user a number was not 'entered

Else

'Otherwise, if the value input was 'numeric

MessageBox "You entered a number!"

'Tell the user a number was 'entered
