Dude, your macro is working but now everything has changed. This is the full macro i am using: 

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)Const WORKING_DAY_START As String = "09:00"
Const WORKING_DAY_END As String = "18:00"
Const FORMULA_WORKING_TIME As String = _
    "=(INT(E2-D2)*(""" & WORKING_DAY_END & """-""" & WORKING_DAY_START & """)" & _
    "+MEDIAN(MOD(E2,1),""" & WORKING_DAY_END & """,""" & WORKING_DAY_START & """)" & _
    "-MEDIAN(MOD(D2,1),""" & WORKING_DAY_END & """,""" & WORKING_DAY_START & """))"
Const FORMULA_ELAPSED_TIME As String = "=F2-D2"
Dim lastrow As Long

    With Me

        'input Elapsed Time
        .Range("H2").Resize(lastrow - 1).Formula = FORMULA_ELAPSED_TIME
        
        'input First Response time
        .Range("G2").Resize(lastrow - 1).Formula = FORMULA_WORKING_TIME
        
        With .Range("G2:H2").Resize(lastrow - 1)
            .Value = .Value
            .NumberFormat = "[h]:mm_w"

If i use your Macro, everytime that i enter an "extra time" it will adjust The Elapsed Time value and it is correct but something is wrong because if i put an extra time and double click again on Date of the problem/Date First Response/Date Last Response it will put the original value on "The Elapsed Time" cell and thats not correct. It should not modify anything! (PS: i have to double click on "extra time" to modify the value stored in "The Elapsed Time" and in my previous Macro it was not necessary)


Also, if First response and Elapsed time have a value >, < or equal to the other values (depending on the priority) it will have a different colour but with your Macro it has stopped working properly. Why?

Could you please help me to solve this mess?
