instr problems - finding sometimes, not other times.

Hi Experts,

I am using ASP classics instr to find a sting withing a long string:

The Long String:
<p>Hi there <session>FirstName</session>,</p><p>We recently received a request to add this email address <querystring>EmailAddress</querystring> to hopefully your <field1>LocalURLshort</field1> account.</p><p>If this was you, please click this link to verify the email belongs to you:</p><p> <field>VerifyLink</field> </p><p>If for some reason someone has put your email in by mistake, please ignore this email, sorry for bothering you.</p><p>If this has happened a few times, then report this person to us by clicking this link:</p><p> <field>ChangedName</field> </p><p>We will ensure they cant do it again.</p><p>Thanks for your support.</p><p>GigTxt Email System</p><p><field1>LocalURL</field1></p><p><field1>GigTxtSignature</field1></p>

The Needle
As you can see I do a search and replace for "<field>something</field>" and "<field1>something</field1>"
My issue is this:
I can't seem to get the instr to work the second time around on "<field>something</field>"
I have tried:
Changing the contents between the <field></field>
Putting it with <field1></field1> = this works, but I need to separate them?
changing the field name in the long string from: function, funct, fnc, field1 to finally field

Any ideas would be greatly appreciated, I am at a total loss as to why this is happening on this field in particular??

I fixed it ! Somehow?

Line 23 is now
      i = instr(i, strEmailBody, "<field>") + 1

And that appears to make it work?
No idea why/ how.  As it is different from all the others.

Your function appears to be calling additional functions mid2 and instrRev which you did not post the code for.  Could you post the code for these routines?

I am actually unclear about what you are trying to accomplish.  Could you be more specific.  I see the long string input.  
Could you provide:  
     (1)   what you would like the output to look like
     (2) what the variables are and where they come from which are used to build the
           output.  For example, the FirstName variable comes from the session.  The
           emailAddress comes from the querystring, etc.

Hi,

instrRev is a standard ASP function that is just instr, but looks from the end instead of the start
mid2 does exactly what Mid does, but mid was causing all sorts of issues, as per
http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/ASP/Q_23789358.html

1.
The output will look like ( removing the <field> etc and replacing with a string)
The Long String:
<p>Hi there FirstName,</p><p>We recently received a request to add this email address Email@test.com to hopefully your LocalURL account.</p><p>If this was you, please click this link to verify the email belongs to you:</p><p> VerifyLink </p><p>If for some reason someone has put your email in by mistake, please ignore this email, sorry for bothering you.</p><p>If this has happened a few times, then report this person to us by clicking this link:</p><p> ChangedName </p><p>We will ensure they cant do it again.</p><p>Thanks for your support.</p><p>GigTxt Email System</p><p>LocalURL</p><p>GigTxtSignature</p>
2.
The varialbles are
<field> - gotten by running a function in long term, but just using a simple string in this case
<field1> - looks up a value in the Db
<session> - a session variable (ie. inside the tags is the name of the session variable)
<querystring> - as I converted this to a function, it is now a Parameter of the function

Problem Variables are
VerifyLink
ChangedName (was BlockLink)

These are <field> type at the moment.  I have tried <funct>, <fnc>, <test>, <field1> and now <field>


Function Mid2(strFind, strInput, j)
 
	Mid2 = right(strInput, len(strInput) - instr(j, strInput, "<" & strFind & ">")-len(strFind)-1)
	Mid2 = left(Mid2, instr(1, Mid2, "</" & strFind & ">")-1)
	
	response.write "<br>Mid2:" & j & " :" & Mid2 & "<br>" & vbcrlf
 
End Function
