    Javascript Subroutine Problem

    The following line of script code works correctly:

    Code:
    w('<input type=radio name=rad onclick="myImg.src=\'../Audio Streaming/'+myPhoto+'\';">');
    When onclick is executed, the variable "myPhoto" is correctly loaded as the source for "myImg" which is then displayed.

    I need to accomplish several tasks when "onclick" is executed and I am trying to setup a subroutine "mySub" to perform the various tasks. I created a subroutine as follows, located in the <body> of the html routine.

    Code:
    <sub mySub(x)
{
myImg.src=\'../Audio Streaming/'+x);
}
    I replaced the above line of code with :

    Code:
    w('<input type=radio name=rad onclick="mySub(myPhoto)">');
    to pass the parameter "myPhoto" to the subroutine, but I keep getting the error message "Object Expected".

    Can anyone tell me what I am doing wrong?

    Thanks - Patrick Russell

      I can't see where myPhoto is defined in the scope of what you're doing....do you have any more javascript on the page?

          Yes I do have other javascript. The major portion is as follows:

          Code:
          function w(s)
{
	document.writeln(s);
}
var previousSpeaker="", previousSeries="";					// initialize variables to empty string
for(var i=0; i<parent.audio_info.length; i++)  				// loop through all listed audios
{
	var sermon=parent.audio_info[i];        				// get next audio as an array of 5 strings
	var mySwf=sermon[0];	// Streaming Audio "swf" file
	var mySpeaker=sermon[1];	// Speaker's Name
	var myPhoto=sermon[2]; 	// Speaker's "jpg" photo
	var mySeries=sermon[3]; 	// Sermon Series Title
	var myTitle=sermon[4];	// Sermon Title

	if(mySpeaker!=previousSpeaker || mySeries!=previousSeries)  // new speaker or series?
	{
		w('<br><span style="font-family: Swis721 Blk BT">');
		w('<font size="4" color="#333399">');
		w(mySpeaker);
		w('</font></span>');
		w(' : '+mySeries);
		w('<br>');
	}
	w('<input type=radio name=rad onclick="mySub(myPhoto)">');
	w(myTitle);
	w('<br>');
	previousSpeaker=mySpeaker; 
	previousSeries=mySeries;
}
          Code continues ... Basically, the user selects a radio button from a list, from which the correct sermon tiltle and audio flash file are extracted and used.
