multiple frame-update

Hello,

I try to update several frames in one mouseclick. There is an error in the

code below, that is for sure. The Text-frame doesn't get updated. What do
I 
do wrong?

Thanks,

Sjoerd




<a href="Mirte.htm"
   target="Info"
   onclick="if (parent.frames.Play) {
                 parent.frames.Play.location.href = 'PlayMirte.htm';
               }
               and
           if (parent.frames.Text) {
                 parent.frames.Text.location.href = 'Text0000.htm';
               }
               return true;">
Mirte
</a>
