ImportXML function error in Google spreadsheet

I'm trying to use the ImportXML function in Google Spreadsheet for my business.

From this link: http://ift.tt/1EzvMJ4

I need for example container number MSKU7754081

So my function looks like this

=importxml("http://ift.tt/1EzvMJ4";"//html/body/div[1]/div[2]/div[3]/table/tbody/tr/td[2]/span[1]")

But it shows N/A and error -Imported content is empty.

Please assist

Thanks in advance
