Have 2-txtboxes, where user enters date. I'd like to know the number of days between the entered dates:

If DateDiff("d", Me!txt0, Me!txt1) > 5 Then
Msgbox "5+"
End If

but I'm getting "Type MisMatch"

any ideas....

This can only be if the value in the textboxes is not a valid date

Try to check using the IsDate(Me!txt0.Text) if the value is recognized as a date or not.

Hi Debbie790,

-you should be sure there are dates entered in the textboxes
-make their format property something like short date
-and then you can do something like

If DateDiff("d", CDate(Me!Txt0), CDate(Me!Txt1)) > 5 Then

-and better rename your date boxes to something meaningful for easier reading

DateDiff works on Date/Time field values.  It does not convert Text fields to Date/Time on the fly.  You can try the CDate function to convert a text string to a date before using datediff.

If DateDiff("d", CDate(Me!txt0), CDate(Me!txt1))>5 Then
    Do stuff here
End If
