Counting number of submits to an html form

[Keith Kurzendoerfer]

I have a very long html form with many loops in it. I'm trying to

keep track of how many times a user hits a specific web page while

they are filling out the form. To do this, I have a "ctr" field and

some CDML code on the page I'm trying to track that should add 1 to

the current value of the counter each time the user hit's the submit

button. The code looks like this:

<input type="hidden" name="ctr" value="[FMP-Field:ctr] + 1">

Unfortunately, when the information is written to the database, it

doesn't calculate the math. The field ctr will contain the value

"0+1" or "0+1+1" and not the value "1" or "2".

Any ideas?

Thanks!
