Help needed , How to use save in single/mutiplayer alone

[Mr.Cheater]

Map name : Terrainia v110 Prot

I just started learning how to [deprotect/insert JJCP/enable SP] today but i encountered lots of problems.
Firstly, I tried finding if the map have bj_isSinglePlayer n after tht i found

set bj_isSinglePlayer=false
set aN=0
set iN=0
loop
exitwhen iN>=$C
if(GetPlayerController(Player(iN))==MAP_CONTROL_USER and GetPlayerSlotState(Player(iN))==PLAYER_SLOT_STATE_PLAYING)then
set aN=aN+1
endif
set iN=iN+1
endloop
set bj_isSinglePlayer=(aN==1)

Is tht whr i delete it ? n saving in multi/single player doesnt work for 1 player

post the map or the war3map.j
you need to change a different part of the script
