Javascript Subroutine Problem

The following line of script code works correctly:

Expand|Select|Wrap|Line Numbers

 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.

Expand|Select|Wrap|Line Numbers

 <sub mySub(x)

{

myImg.src=\'../Audio Streaming/'+x);

}

I replaced the above line of code with :

Expand|Select|Wrap|Line Numbers

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:

Expand|Select|Wrap|Line Numbers

 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.
