Cannot read property 'match' of undefined

Dear Supsystic,

After updating your plugin last week, a website of our client shows an error, and stopped working.
As you’ve mentioned a “bugfix” in currency formatting, I’m suspecting this is where things go wrong.

Uncaught TypeError: Cannot read property ‘match’ of undefined —> tables.shortcode.js?ver=1.3.7:41

$(document).ready(function () {
		$('.supsystic-table').each(function () {
			var table = $(this),
				format = table.data('currency-format'),
                		formatWithoutCurrency = format.match(/\d.*\d/)[0],
               			currencySymbol = format.replace(formatWithoutCurrency, '') || '$',
                		formatDelimiters = (formatWithoutCurrency.match(/[^\d]/g) || ['.', ',']).reverse(),
                		delimiters = {
                    			decimal: formatDelimiters[0],
                    			thousands: formatDelimiters[1]
                		}, ...etc.

The ‘formatWithoutCurrency’ part is row number 41.

Could you please work out a solution to this error?

Thank you in advance, thumbs up for a beautiful plugin!
