Hello!

I am trying to use Form API 2.0 to create a multipage form. I follow this article: http://drupal.org/node/101707.

The problem is: if I do not put the $form_values as the first parameter I cannot get it, and the first one is the real $form_values.

So if my function is my_form($form_values), it is ok. If my function is my_form($param, $form_values), the data from form page 1 will be stored in $param but not $form_values.

Hi,

I would like to use the revisions with 4.6,
I use the function node_revision_create($node) each time I update the node but it doesn't work!
Did anyone have this problem before?

I currently use the Drutex module to show different math problems and solutions on my website. It certainly does look good, I've never even imagined it's possible, you can take a look at the result on www.studentblock.com under the "My first day in MA 275." My question is whether it is possible to make the code a little bit more simple, so I don't have to type $\frac, \cdot or other commands all the time.

This is a very strange error message considering that it's occuring on a development site which is an exact copy of a production site, they have the same database and files, paths to files and tmp directory are same.
