Error With Multipliers

IT LOOKS TO BE WORKING FINE NOW!

I was changing different configurations and disabling and enabling plugins ( I had a old version and i see there new and different extensions.

I was wondering if this custom code you create for me long time ago is still needed.

// JavaScript Document
/**
 * jQuery extension for the Football Pool plugin
 *
 * The script combines the input values of all prediction forms on a page and submits all the values. With the fp-predictionform
 * shortcode you can put multiple forms on a page (and maybe separate them on tabs). This script enables users to submit all these
 * forms with either one of the submit buttons.

jQuery( document ).ready( function() {
	// add submit handler to all football pool prediction forms
	jQuery( 'form[id^=predictionform-]' ).submit( function( e ) {
		// store the form that was submitted
		var submitted_form = jQuery( this );
		// get all other forms to attach the inputs to the submitted form
		jQuery( 'form[id^=predictionform-]' ).not( submitted_form ).each( function() {
			var this_form = jQuery( this );
			// get all the match inputs from the form and attach as hidden input to the submitted form
			jQuery( 'input[name^=_bonus_], input[name^=_home_], input[name^=_away_]', this_form ).each( function() {
				var input = jQuery( this ).clone();
				input.attr( 'type', 'hidden' ).appendTo( submitted_form );
			} );
		} );
		// set form id to first form so save action is always triggered on first shortcode
		var first_form = jQuery( 'form[id^=predictionform-]' ).first();
		var first_form_id = jQuery( 'input[name=_fp_form_id]', first_form ).val();
		jQuery( 'input[name=_fp_form_id]', submitted_form ).val( first_form_id );
		// get the joker value (if set)
		var joker = jQuery( 'span.fp-joker' );
		if ( joker ) {
			var id = joker.first().attr( 'id' );
			var joker_value = id.substring( id.indexOf( '_' ) + 1 );
			joker_value = joker_value.substring( 0, joker_value.indexOf( '_' ) );
			jQuery( 'input[name=_joker]', submitted_form ).val( joker_value );
		}
		// proceed with the submit event
		return;
		// e.preventDefault();
	} );
} );
