Kuba,

If you get resolution to your problem, please post it here. I tried running your code (copied from Pieter's post) and was not able to progress to the second page of the multipage form. I am working on a similar project and had this same issue with the example code provided on Wolfram's Advanced Web Form Creation tutorial. I sent an email to tech support and am currently waiting for a reply. If you find out that it is some sort of settings issue, I'd really like to hear about it.

Thank you

This it the point, change to Print to Console and try.

And about multipage form. I will do further test to narrow this down.

Thanks

Kuba,

1) i tested in chrome, firefox and even IE (latest versions) They all run your code

2) Here are my settings.

Kuba,

Multipage formfunction works fine in the cloud. I tested your code and it works. If I enter 3 in the rooms field it delivers 3 input fields when next is pressed.

CloudDeploy@FormFunction[
  {
   {{"rooms", "number of rooms"} -> "Integer"}, 
   Table[{"room" <> ToString[i], "guests in room" <> ToString[i]} -> 
      "Integer", {i, #rooms}] &
   }]

If you evaluate in the desktop it is also fine. (note the [] at the end to launch the form)

FormFunction[{{{"rooms", "number of rooms"} -> "Integer"}, 
   Function[
    Table[{"room" <> ToString[i], "guests in room" <> ToString[i]} -> 
      "Integer", {i, #rooms}]]}][]

Could you be more specific on what it is that is not working? (I tested 10.1 kernel, win7 64)
