I just looked at your code from the previous post.
I think this error came because you defined ParseArgs twice, first you
gave it a string value, and then an array:

A) $ParsedArgs['location'] = str_replace('"', '',$params['location']);

B) $ParsedArgs['location'] = array( 'lon' => $ll[0], 'lat' => $ll[1] );

I suggest to add 'location' to the $GoogleMapDefaults array,
'location' => '',

then inside function GenerateMap do this:

function GenerateMap( $params ) {
   global $GoogleMapDefaults, etc...;
   $opt = array_merge($GoogleMapDefaults, ParseArgs($params));

and then work with $opt['location'], $opt['lon'], $opt['lat'] etc.

if($opt['location']) FindCoordsForLocation($opt['location']);

etc.

So in your wiki page markup you use:
  (:map location="string...":) or (:map lon=.. lat=... width=..
  height=...:)
just have all your parameter keys defined in $GoogleMapDefaults.

As to the ?HeadFmt problem: I would only use $HTMLHeaderFmt, and use
the $opt['lat'] and $opt['lon'] to create the correct javascript entry
to initialise the map.

Hope this helps a bit an dis not too confusing.
