Javascript looping through dynamic forms

Please can someone help out with this? To reiterate, I am looking for a script that will accept an ASP variable for the number of text items on in the form (as this is done dynamically). Then I wish to total the elements (be it 5 or 50) and alert if it is over a specific total, say 100.

It would be something like...Onsubmit the following function would fire:

Loop through all form elements (there will only be text boxes called text<%=n%>)
If form.elements.total > 50
Alert ("you have exceeded your limit, please amend your data")

Hope that helps

Thanks

For x = 1 to Request.Form("Catalogid").Count
If val(Request.Form("qty_Ordered")(x)) > 0 then
Mfound = true
end if
next


You can add up your fields values and then when your html redisplays you could show a message that your over 100?

Hope this help!
