thanks,

you on right track saving text in $cus_fullname in leave callback never use $cus_fullname set text when creating page, seem try ${cus_fullname} instead!

it should more this:

${nsd_createtext} 60u 50u 60% 11u "${cus_fullname}" pop $0 ${if} $cus_fullname != ""   ${nsd_settext} $0 $cus_fullname ${endif} ${nsd_onchange} $0 update_acustompage_next_button 

here standalone example:

!include nsdialogs.nsh  var hctlfullname var fullname  function mypagecreate nsdialogs::create 1018 pop $0  ${nsd_createtext} 60u 30u 60% 11u "$fullname" pop $hctlfullname ${nsd_onchange} $hctlfullname mypage_verifyinput  call mypage_verifyinput nsdialogs::show functionend  function mypageleave ${nsd_gettext} $hctlfullname $fullname functionend  function mypage_verifyinput call mypageleave ; loads text $fullname push $0 getdlgitem $0 $hwndparent 1 ${if} $fullname == ""     enablewindow $0 0 ${else}     enablewindow $0 1 ${endif} pop $0 functionend  page custom mypagecreate mypageleave page components page instfiles  section detailprint $fullname sectionend
