Output integer from snippet - how?

I want to output an integer from a snippet but I can't get it to work. So I reduced the snippet to something simple, and it still doesn't work

In the chunk there's only When I use the chunk, <p>test chunk is [[$test_chunk]]</p>, it's blank, ie it returns, test chunk is

What am I doing wrong?

Thanks Bob. Now I know I'm not explaining this properly, as the reason I had is that the snippet is a custom hook and they need to return true. If you'd known it was a hook you'd have given a different answer.

All I'm trying to do is use a custom hook to return a form value for Formit redirectTo. Since I've tried everything I can think of I thought maybe I need to output to a chunk, then maybe multiply by 1 to turn it into an integer then use the chunk as the redirectTo value. But nothing I try works - they all end up as an error "`[[...]]` is not a valid integer and may not be passed to makeUrl()"

Any help welcome.

Ah, then put this just above the return:

Well, that works nicely, thank you, but here's the crux of the matter. Why can't formit's redirectTo also use [[+gotopage]]? The number's in the placeholder, the chunk is displaying the placeholder, the email is displaying the placeholder, but redirectTo stubbornly refuses.
I noticed another long thread about roughly the same issue with redirectparams. Is it not possible to use a placeholder for redirectTo?

It ought to be possible, but the snippet that sets the placeholder would have to be above the FormIt tag.

I don't see how that could work though, as the value of redirectTo comes from a form value: ie redirect page varies with number-required.

In any case, if &emailTo can use the output from a form field, and the email hook is processed by Formit before the redirect hook, why can't &redirectTo also use the output of a form field?

Try making your snippet that sets the placeholder the first hook in the list. I don't think it will work, but it's worth a try. If it doesn't, this should definitely work.

Leave out the redirect hook and make your own MyRedirect hook (something like this) and put it last in the list:



If there are no params, you can do it like this:

Thanks for that Bob, but I'd already tried using I just used makeurl with the 'number-required' value and it worked fine. The problem was that on the receiving form, there were no stored values for Formretriever. Switched back to redirectTo, previous form values are retrieved, switched to sendRedirect, values aren't stored. Looked like Formretriever relied on the redirect hook to work. Is there such a coupling?
