    Then why this not working ?

    End If

    Because EditTex1.Text is a String Value and 3 is an integer. You would need to convert your EditText1.text to an int prior to comparing it.

    You also should have some error checking so that you EditText1.text really is a number and not something like "Hello3"

    if val(Edittext1.text) < 3 then
    ' I'm lower then 3
    ' I'm greater then 2
    end if

    To check if Edittext1.text is really a number:
    If IsNumber( Edittext1Text) Then .......

    The Val() function will also do this for you but will return 0 if .Text is not a real number. So on EditText boxes controls it is best to check that what the user entered is
    really a valid number not something else. Sometimes it best just to use a spinner control for numbers only.

    Here you go @G-ShadoW...
    Sub Globals
    Dim EditText1 As EditText
    End Sub

    Sub Activity_Create(FirstTime As Boolean)
    Activity.AddView(EditText1, 50dip50dip100dip60dip)
    End Sub

    Sub ET1_TextChanged (Old As String, New As String)
    If EditText1.Text < 5 Then ToastMessageShow("Smaller"False)
    End Try
    End Sub

    There is no Val keyword in B4A. The compiler will automatically parse the string to a number. You can use IsNumber to test whether a string can be safely parsed as a number.
