Hello Guyz...

I have a form with a field where the user must insert his birth date. On submit I check the value if it is a date and then if this date is between logical limits. But I have a prob. The code I wrote is the following.

<form action=update_new_user2.asp method=post name=frmupdate>
    <input type=hidden name=Action value=Update>

<table>
        <tr>
        <td>Birth Date</td>
        <td><input type=text name=a4 size=30</td></tr>


<tr>
<td height=60><input type=button name=btnSubmit1 value=Insert></td>
</tr>
    </table>
     </form>


<script language=vbscript>
Sub btnSubmit1_OnClick()


If Len(frmupdate.a4.value) = 0 OR NOT IsDate(frmupdate.a4.value) Then
Alert "You have to insert date (dd/mm/yyyy)"
    frmupdate.a4.focus
    Exit sub

       ElseIf (frmupdate.a4.value) < "1/1/1940" OR (frmupdate.a4.value) > "1/1/1980" Then
        Alert "You have to insert right date"
        frmupdate.a4.focus
        Exit sub
End If

    Call frmUpdate.submit()
End Sub
</script>



The problem with this code is that if the user try to insert for example 1/1/1960 everything will work fine. But if he try to insert 2/1/1960 or anyother value for month and date other than 1/1 then the senond Alert box comes up.

Plzzz... help me with that..

hi there.. you are making the comparations like there where strings, not dates..
i dont konw how to do it in script.. maybe you have datediff=???
or something like that to convert every to date???

other things i do is to format dates like yyyymmdd, and then compare them in string.. always work...

HTH

Your reply is very helpful. I think that I have to convert it to a string like yyyymmdd eventually although I would like to avoid this.

But if I should use "substrings" then I think that it would be better if I use 3 listboxes (dd)(mm)(yyyy) [than using a simple "textbox"] in order to make the date again.

What`s your opinion about that?

P.S. I`m just looking for the easier best solution :P
P.S. [I`m a newbie!]

I solved the problem. And actually it was quite easy to be used!

ElseIf (Year(frmupdate.a4.value)) < 1940 OR (Year(frmupdate.a4.value)) > 1980 Then
        Alert "You have to insert right date"
        frmupdate.a4.focus
        Exit sub
End If


-------------
this is the solution. (Year(value)) returns yyyy.
I feel good to solve this and a bit stupid that I had a prob like this...
