[Ali7021]

Please check my script and guide me what is issue is there . I want to do offset 2145 to 520 ahead.

 

function wol() 

gg.searchNumber('   3D;11D;2145D ', gg.TYPE_DWORD,false, gg.SIGN_EQUAL, 0, -1) 
gg.refineNumber(' 2145 ', gg. TYPE_DWORD)
local start = gg.getResults(1)
local target = start[1].address + 0×520
gg.setValues({ address = target , flags = gg.TYPE_DWORD, value = 10})
gg.toast(' MISSION HACK ') 
gg.clearResults() 
gg.alert(" Play Denomination mission in easy level with Ace deployed") 

home = 1 
end
