Hi

Can someone see what is wrong with the jquery below:

I get an parseInt(".mnumber").text is not a function
('.mnumber').html((parseInt('.mnumber').text())*0.39);
      

$(document).ready(function(){
       $("#select_cm").click(function() {
            convert('cm');            
      });
      });
      
      $(document).ready(function(){
      $("#select_in").click(function() {
            convert('in');                  
      });
      });
      
      function convert(metric) {
            switch(metric){
            case 'cm':
            alert('hello');
            ('.mnumber').html((parseInt('.mnumber').text())*0.39);
            break;
            case 'in':
            ('.mnumber').html((parseInt('.mnumber').text())*0.39);
            break;

First, you don't need multiple document ready functions.  This might be what is causing the problem.
It also looks like you are missing the jquery($)  within you case statements.

$(document).ready(function(){

       $("#select_cm").click(function() {
            convert('cm');            
      });
     
      $("#select_in").click(function() {
            convert('in');                  
      });
      });

      function convert(metric) {

            switch(metric){
                 case 'cm':
                      alert('hello');
                      $('.mnumber').html((parseInt('.mnumber').text())*0.39);
                      break;
                 case 'in':
                      $('.mnumber').html((parseInt('.mnumber').text())*0.39);
                      break;
            }
      }

Hi

Thanks - that's a great help however there it still throws error:

parseInt(".mnumber").text is not a function
$('.mnumber').html((parseInt('.mnumber').text())*0.39);

try:

$('.mnumber').html(parseInt(('.mnumber').text())*0.39);

It might be a problem with your parenthesis.
parseInt(  ('.mnumber').text()   )
