just wanted to ask how to put message in another line after the other. Here's my code in my program:

function isEmpty(field,name,minVal, maxVal){

  var msg =;

  if (field.val() >= minVal || field.val() <= maxVal){

    if ( field.val().length == 0){ 

      msg=(name + ' is empty.n');

    }

  }

  else{

    msg=(name + ' inputted is invalid or number is more than 1000. n');

  }  

  return msg;

}



function validateTallyReq(par){

  var msg= Please read the following:;



  msg += isEmpty($('#tallyPlankNo'),'Plank Number ',1,999) ;        

  msg += isEmpty($(#tallyThick), 'Thickness value',.9,999);

  msg += isEmpty($(#tallyWidth), 'Width Value',.9,999);

  msg += isEmpty($(#tallyLength), 'Lenght Value',.9,999);

  msg += isEmpty($(#tallyQty), 'Quantity',1,3);



  if (msg == )  { 



  } else {

    showMessage(msg);    

  }

  return false; 

}

this outputs message in one line. What I want is the message to output like:

Please read the following:



Plank Number is empty. 

Thickness value is empty. 

Width Value is empty. 

Lenght Value inputted is invalid or number is more than 1000. 

Quantity is empty. 

And one more question, I really dont know why it shows the length value is invalid though i dont input any value on it,. Please help.

EDIT

This is my showMessage function:

function showMessage(msg) {

  $('#dialog #message').text(msg);

  $('#dialog').dialog('open');

}
