<p class=MsoNormal>Afternoon all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m hoping someone will be able to look through the
code I have to dynamically set the initial map position and scale. I have taken
this straight from the code sample (<a
href="http://trac.osgeo.org/mapguide/wiki/CodeSamples/PHP/InitialMapView">http://trac.osgeo.org/mapguide/wiki/CodeSamples/PHP/InitialMapView</a>)
but when I run it, it just opens the map up at the default scale level. Any
help would be greatly appreciated...<o:p></o:p></p>

<p class=MsoNormal>I am passing in X, Y and Scale as parameters within the
