Default help on functions instr....

I am writing a function to keep the values between the content class when i search an html page because I just want the text between the content class to be searched, but it keep giving me errors.

iPos = InStr(1,orig_string,"<p class=""content"">")

<%
Function Remove(orig_string)
iPos = InStr(1,orig_string,"<p class=""content"">")
If iPos = 0 then
strTitle = "Untitled"
    Else
strTitle = Mid(orig_string,iPos+21,InStr(iPos,orig_string,"<p class=""content"">")-iPos-21)
End If
orig_string=strTitle
End Function
%>

    contValue = "<p class=""content"">Monsignor Frank Rossi - Director<p class="content">"
x= remove(contValue)
response.write x

I can see a few things here:
1. in your test string (contValue=...) you haven't doubled up the quotes around the ending "content"
2. in this line: strTitle = Mid(orig_string,iPos+21,InStr(iPos,orig_string,"<p class=""content"">")-iPos-21) you need to start the InStr at iPos+1 not at iPos
3. your iPos+21 and iPos-21 should be iPos+19 and iPos-19 because the double quotes don't actually exist in the string variable orig_string

I'm confused about one thing though, in that line contValue = "<p class=""content"">Monsignor Frank Rossi - Director<p class="content">" , shouldn't the ending tag be just </p>? Or is it the starting tag for another para element?
