AH-SID Aash you should add:

var $device =<xt:get_device_template>

if $device ==mobile
var $entries_per_page =3
var $display =1
else
var $entries_per_page =5
var $display =2
endif

put that codes in first line of <!--parser:xtscript-->

next, you should edit entries_per_page and display become:

entries_per_page="$entries_per_page" display="$display"
