Hi Antonio,

Set century is on and date format is mm/dd/yyyy. Is this the one your asking?

Here is the code: .OleDatePicker4.Change (EndDate)

LOCAL lcMonth, lcDate, lcDay, lcYear, lcTime

With This
     lcDay   = STR(.Day,2)
     lcYear  = STR(.Year,4)
     lcMonth = STR(.Month,2)
*     lcTime  = str(.Time())
     lcDate  = lcMonth +"/" + lcday+"/"+lcYear

     WITH ThisForm
          .txtEndDate.Value=ctod(lcDate)
*          .txtEndDate.setfocus()

**** Check if end date (.OleDatePicker4) is earlier than start date (. (OleDatePicker3)
		 IF .txtEndDate.Value <= .txtStartDate.Value
	             .txtStartDate.Value=.txtEndDate.Value - 1

*** Replace the following 
		     .OleDatePicker3.Month=MONTH(.txtStartDate.Value)
		     .OleDatePicker3.Day=Day(.txtStartDate.Value)
		     .OleDatePicker3.Year=Year(.txtStartDate.Value)

		 ENDIF		 		 
     ENDWITH     
ENDWITH

the error happens only on these dates between April 1-3, for example when startdate is April 2 and enddate is april 3, when i change enddate to april 1, startdate shlould change to Mar 31. but it doesn't change on the date picker and this error message appears, but it does change the value on the (textbox) .txtStartdate


Thanks,

Sonny
