<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi everyone,<br>
<br>
I've just started a new project, modifying the tutorial about the Stokes problem contained in the package Dune-Fem-Howto.<br>
<br>
I don't know why, but it seems to be a problem in one of the inclusion: (probably all the errors come from the first line)<br>

<div>Does anybody have the same problem? <br>
I've simply copied and pasted demo codes. I don't know if I have to define additional variables to make it work.<br>
<br>
Cheers, <br>
