i have an alert(MyCommentsTableField) in my code. Problem is sometimes the comments may have special charaters like maybe ( I'll .... we'll ..."" ..... ) and i think then cause the alert funtion not to work.

how can i test for invalid characters and then strip them off before calling the alert function?

No no....... MyCommentsTableField is a "memo" field in Access or "ntext" in SQL2000.

The comments is free format TEXT that is entered in a field just like a normal comment for say a Customer record. Typical comment may be like

"Joe called on 12/8. He's a high risk .... so check credit limit or request "guarantor" ... !!!!!!"

In my query .. I do say
SELECT Cust_Id, Cust_Name, Comments from CUSTOMERTable

if Comments <> ''
alert(Comments)
end if


But because it is free format text ... Comments may contain "invalid" characters ... so I think I want to kind of validate the TEXT or PARSE the text for any characters that may prevent alert(Comments) from working.

Or is there no need for that?

just make an array of all the invalid characters which are most likely '"/\;:$ and probably a couple more. In your array you would list each invalid charachter and have the textboxes check the array onpropertychange, and if it finds one of those invalid characters, then it would alert them or some other fansy way...

easy as pie...

oh, or you could just use a confirm box. That way you could skip writing the array syntax!

Oh ok. Try this.

Code: 
SELECT Cust_Id, Cust_Name, Comments from CUSTOMERTable

if Comments <> '' %>
<script language=vbscript>
msgbox(Comments)
</script>
<%
end if

There are no invalid characters for an alert box. If your MyCommentsTableField string contains the text, then the alert box routine should show it.
