I ran the code you recommend me. However, anytime I enter the same date or different dates, vba displays error 13 in this line:
If DateValue(Me.txtday1) = DateValue(Me.txtplot) Then
I have been trying by my self to fix such error with no success.
Could you suggest me how to fix the code?
Once again many thanks
