HELLO MAPSERVER USERS!

What I try to do is center to the selected feature in current map 
extent. How can I zoom to selected feature (features). I know that I 
should use some syntax with [shpmid] but I DON'T KNOW HOW TO DO THIS.

PLEASE HELP ME to dissolve my little problem ?

In my map file I have "doubled shapefile":

LAYER

NAME PLOT

  DATA Cataster

STATUS ON

TYPE polygon

LABELITEM "NUMER"

LABELMAXSCALE 5000

TRANSPARENCY 10

CLASSITEM "NUMER"

CLASS

COLOR 245 245 220

OUTLINECOLOR 0 0 0

TEMPLATE "dzialki.html"

LABEL

COLOR 0 0 0

TYPE BITMAP

FONT arial-bold

SIZE SMALL

ANTIALIAS TRUE

POSITION CC

PARTIALS FALSE

MINDISTANCE 250

BUFFER 4

END

END

HEADER "dzialki_header.html"

FOOTER "dzialki_footer.html"

END

#------------------------------------------------------

LAYER # Query

NAME QPLOT

DATA Cataster

STATUS OFF

TYPE polygon

CLASSITEM "NUMER"

CLASS

# EXPRESSION ([NUMER] eq [value])

COLOR 255 50 10

OUTLINECOLOR 0 0 0

END

END

In my html file I use this syntax:

<input type="hidden" name="layer" value="Qdzialki">

<input type="hidden" name="map_Qdzialki_class_expression" value="[NUMER]">

<input type="text" name="map_Qdzialki_class_expression" size="5" 
maxsize="9" value="">

and it's work fine. If I put some number in txtbox I get in the map 
window selected feature. But I ask one more time:

DOES ANYBODY KNOW HOW TO ZOOM TO THIS(THOSE) SELECTED FEATURES?????
