You can use a macro -- but that would only work if macros are enabled by the
user.

Option Explicit
Sub Auto_Open()
thisworkbook.worksheets("Somesheetnamehere").range ("x99").value = 0
End sub

If you're new to macros:

Debra Dalgleish has some notes how to implement macros he

David McRitchie has an intro to macros:

Ron de Bruin's intro to macros:

(General, Regular and Standard modules all describe the same thing.)
