Thank you.
I think I have minimized my problem to this whole coordinate thing. What =
I noticed is that my code does not catch "extent" as it works. I have to =
feed it with the beginning coordinates myself. I have changed the code a =
little bit too. Now it can move the map to left, but only the original =
map, not the zoom map. I think my problem is that I cannot "catch" the =
coordinates/extents of the last map drawn. It has something to do with =
this line:
$extent_to_set =3D explode(" ",$HTTP_POST_VARS["extent"]);
When I run the second europa example from mapserver site the same line =
works and prints the picture. In my case, it produces this error:
Fatal error: MapServer Error in msCalculateScale():=20
referring to the line with the "explode". The EXTENT in europa is in =
this format:
EXTENT -5696501 1923039 5696501 11022882
whereas mine is:
EXTENT 29.057 40.954 29.143 40.999
My extents work with the mapserver itself. When I check a regular map =
from an atlas, I see they use my type of coordinates. It appears my =
geograph is not so well at all!
I suppose this is related to what Mr.Bridger discussed in his reply mail =
but how related is something I didnt understand. Any ideas?
BTW: I am using php-mapscript-3.6.0-4, installed by rpm. May the version =
be related? Bug or something?
Have a nice day:)

current php code: (if needed I can also send my mapfile. I am not =
sending now not to take much space in your mailboxes...)
