I have recorded the Sub "Add_to_List" as detailed below and attached it to a
button on my spreadheet.

What lines would be required to add the condition that the macro will only
proceed:

IF cell D4010 is a date AND cells F4010 & G4010 are interger numbers
Carryout Macro ADD_TO_LIST
ELSE provide a messagebox that states, "Cell D4010 must be a date AND cells
F4010 & G4010 must be interger numbers"

Many thanks

Neil
