multiple datepicker with yearRang option set in one form causes error

I use the datepicker in multiple sections of one form.

Within the head area of the site i initialize the datepicker for the class datepicker. Afterwards before the specified inputfields willbe generated in the code i implement a small js section which sets the yearRange option for the specified id.What now happen, is that the first datepicker get the correct parms and show the decided yearRange but the second one show up with standard range ('option', 'yearRange', 'c-10:c+10').

I wasn't able to find an error in my code thats why i guess it depends on the datepicker plugin itself.

Below the code snippets i use.

Here jquery will be initiated and the default values for all datepicker will be set:

//----------------------------------------------------------------------- jQuery
$RET .=
      '<link type="text/css" href="' .
      '../js/jquery/css/smoothness2/jquery-ui-1.8.2.custom.css" '.
      'rel="stylesheet" />' .
      '<script type="text/javascript" src="' .
      '../js/jquery/js/jquery-1.4.2.min.js"></script>' .
      '<script type="text/javascript" ' .
      'src="../js/jquery/js/jquery-ui-1.8.2.custom.min.js"></script>';
//------------------------------------------------------- jQuery Datepicker init
$RET .=
   "<script type='text/javascript'>" .
      "$(document).ready(function() {" .
         "$('.datepicker').datepicker({" .
            "changeMonth: true," .
            "changeYear: true" .
         "});";
if ($RP['l'] == "de"): //---------------------------------------- Language Check
	  $RET .=
	     "$('.datepicker').datepicker('option', 'dayNames', " .
	     "['Sonntag','Montag','Dienstag','Mittwoch','Donnerstag','Freitag'," .
	     "'Samstag']);" .
	     "$('.datepicker').datepicker('option', 'dayNamesMin', " .
	     "['So','Mo','Di','Mi','Do','Fr','Sa']);" .
	     "$('.datepicker').datepicker('option', 'monthNames', " .
	     "['Jänner','Februar','März','April','Mai','Juni','Juli'," .
	     "'August','September','Oktober','November','Dezember']);" .
	     "$('.datepicker').datepicker('option', 'monthNamesShort', " .
	     "['Jän','Feb','Mär','Apr','Mai','Jun','Jul','Aug','Sep'," .
	     "'Okt','Nov','Dez']);" .
       "$('.datepicker').datepicker('option', 'firstDay', 1 );";
endif;
$RET .=
         "$('.datepicker').datepicker('option', 'dateFormat', 'yy-mm-dd');" .
      "});" .
   "</script>";

Here's the part which is setting parms for the following datpicker:

//==============================================================================
function sc_DatePicker //----------------------------------------- sc_DatePicker
         ($pNAME, $pDATE, $pWIDTH, $pYRANGE) {
global $SCJQ;
//==============================================================================
return
( "<script type='text/javascript'>"
.    "$(document).ready(function() {"
.       "$('#$pNAME').datepicker('option', 'yearRange', '$pYRANGE' );"
.       "$('#$pNAME').datepicker('setDate', '$pDATE');"
.    "});"
. "</script>"
. "<td class='Td_Memo' style='width:$pWIDTH;'>"
.    "<input name='$pNAME' type='text' style='width:$pWIDTH;' "
.    "maxlength='10' class='datepicker' id='$pNAME' >"
. "</td>"
);
} //---------------------------------------------------- sc_DatePicker ***END***

and here is at least the function call in the form.

   //--------------------------------------------------------------- FL_ValiDate
   "<td class='Td_Memo' style='width:68px;text-align:right;'>$w2</td>" .
   sc_DatePicker('FL_ValiDate', $tempFolder['FL_ValiDate'], '94px', 'c-0:c+2') ."</tr><tr>" .
   //---------------------------------------------------------------- FL_ExpDate
   "<td class='Td_Memo' style='width:68px;text-align:right;'>$w3</td>" .
   sc_DatePicker('FL_ExpDate', $tempFolder['FL_ExpDate'], '94px', 'c-0:c+5') .
"</tr></table>";
//======================================================================= LINE 3

i hope the description is useful and that you can help me.

Many thanks forward.
