You should be using the DateDiff() function

Also, it is not necessary to unprotect the document to use the .Result
property of a formfield.

Use the IsDate() function to check for a valid entry in the date formfields.

One thing I forgot to say, when MSDD1 ...n has the format of +#,##0,
for a negative difference I get "+-14" and a positive difference gives
"+28", so i'm part way there.
