Hi world!

I hope you enlighten me with some ideas why I cannot make this "Next" custom button in Nintex form to work.

I have 2 tabs and a Next JavaScript button. When I click the Next button it should go to the next tab. 

In the "Next" button I added, under Advance -- > Client Click: showTab()

In the Choice Control Setting I added, under Advance -- > Client ID JavaScript Variable Name: varTabButtons

In the Form Setting I added, under Custom JavaScript:

NWF.FormFiller.Events.RegisterAfterReady(function () {
function showTab(sectionid){
var tabControlButtons = NWF$('#' + varTabButtons);
NWF$(tabControlButtons.find('label')asectionid]).click();} ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
});

Also tried this JavaScript code:

function showTab(sectionid){
var rad = NWF$('#' + varTabButtons);
NWF$(rad.find('label')bsectionid]).click();} ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The code above I did find it in the Nintex community site, but none of it worked at all. I get the following error:
Uncaught ReferenceError: showTab is not defined or Uncaught SyntaxError:: Invalid or unexpected token.
 

Thanks
 

Cheers.
 

I.
