How does one determine whether to use Option Compare Database versus or in conjunction with Option Explicit in an Access Form?  When I run analyze performance it tells me to use Option Explicit in my form.  I don't know if this should replace Option Compare Database or be added beneath it.  The code is below
Option Compare Database
 

Private Sub Run_Click()

    Me.Requery

End Sub

You want to use both.  Option Explicit means that you must declare a variable first before you can use it.  This helps minimize compile errors down the road ... and prevents confusion wherein you might use the same variable name twice when you did not intend to.

Add it beneath.  It means you will get an error if you use an undeclared variable.  Without it , any variables used that are not declared with a Dim statement are created as Variants, with all the incumbent overhead.,
