    :confused: 



    If Trim(rstCatItems.Fields("CatNotes") <> "") Then
            If fsoFile.FileExists(Left(Server.MapPath(Request.ServerVariables("SCRIPT_NAME")),Len(Server.MapPath(Request.ServerVariables("SCRIPT_NAME")))-15) + "images\" & Request.QueryString("CatCode") & ".jpg") = True Then %>
              <textarea rows="10" name="CatNotes" cols="34" style="font-family: MS Sans Serif"><%= rstCatItems.Fields("CatNotes") %></textarea>
    Code (markup):
    Can someone suggest what the "-15" number is if

    If UCase(Right(Trim(Request.ServerVariables("SCRIPT_NAME")), 10)) = "#.ASP" Or _
       UCase(Right(Trim(Request.ServerVariables("SCRIPT_NAME")), 13)) = "#.ASP" Or _
       UCase(Right(Trim(Request.ServerVariables("SCRIPT_NAME")), 13)) = "#.ASP" Or _
       UCase(Right(Trim(Request.ServerVariables("SCRIPT_NAME")), 9)) = "#.ASP" Or _
       UCase(Right(Trim(Request.ServerVariables("SCRIPT_NAME")), 15)) = "#.ASP" Or _
       UCase(Right(Trim(Request.ServerVariables("SCRIPT_NAME")), 12)) = "#" Then
    Code (markup):

    Len( Server.MapPath( Request.ServerVariables("SCRIPT_NAME") ) ) -15

    First it gets the Script_Name, then it finds the real path of it (like "C:/inetpub/wwwroot/hello/") then the Len gets the Length of that string

    so it would be the length of C:/inetpub/wwwroot/hello/ - which is 26 (26 characters in that string)

    Then it minuses 26 - 15 which equals 11

    I think I got the problem

    thanks for the pointer

    -15 was counting the filename characters, and deducting. However, I changed the file name and added a _2 to the file name, and as such -15 would change to -17, without this change the path to the right directory could not be established.

    So I need to change -15 to -17!:eek:

    Apparently, there is a better way, and I will post it later

    Thanks

    Apparently, this does exaclty the same, but with no need to specify a num

    response.write

    (Server.MapPath(Request.ServerVariables("SCRIPT_NAME")))

    response.write

    (left(Server.MapPath(Request.ServerVariables("SCRIPT_NAME")), InstrRev(Server.MapPath(Request.ServerVariables("SCRIPT_NAME")), "\")))


    InstrRev the script name....

    :rolleyes:
