First that I can see is that your instr function is not syntaxed properly. It has three parts and you only show two.

Proper syntax should be: InStr(Form_discription,&quot;badword1&quot;,&quot;badword2&quot;)

Hope this helps,

I have got this to work with only one word in the
InStr(Form_discription,&quot;badword1&quot;)=1 THEN
But not two
InStr(Form_discription,&quot;badword1&quot;,&quot;badword2&quot;)=1 THEN
Im close I think

found another problem this code only checks if that is the only word in the textarea
IE if i write &quot;hello badword1&quot; it lets it go but if i just enter &quot;badword1&quot; in the textarea it works
Any ideas

Make sure you are looking for the proper output...

The InStr function returns the following values:
If InStr returns
string1 is zero-length 0
string1 is Null Null
string2 is zero-length start
string2 is Null Null
string2 is not found 0
string2 is found within string1 Position at which match is found
start > Len(string2) 0

Validated_Form = true

IF InStr(Form_discription,&quot;badword&quot;)=1 THEN ....&quot;here i would like to put more words&quot;.......
Validated_Form = false
END IF

IF NOT Validated_Form THEN
%>
<HTML>
<BODY>

ELSE

'with JMail to you mail account. If you send it to a db, make sure
'to remove any possible ' chars.%>
