</span>You should have access to scalars in any mode. What happens when you try?<br>

</span>It is difficult to see what is going on without the actual scheduling<br>
statements, and in general more information. Could you please post at<br>
least the declaration of both scalar and GFs from interface.ccl, and the<br>
corresponding SCHEDULE entries in schedule.ccl? Also, I assume you do<br>
have storage enabled for both? Also useful might be the output of the<br>
schedule tree. You get that by default, but also when running with the<br>
-S option (that aborts the run after the tree has been printed).<br>
