Showing document on mobile

Hi Chaps,

My client wants to be able to show a document on a mobile phone.  The documents are at:  www.scottsproject.org.uk/what-we-do/day-services/lunch-menus

On a phone, if you select 'View' you get a blank screen, so it is necessary to download the file and go through the steps necessary to view a downloaded document.  Is it possible to set a parameter so that the 'view' option works on a phone?

Thank you

Peter
