Default (ask) error satatus 7 when flasing a rom

hy guys,
im new here,
i want to ask, why i'm allways got "error status (7)" when flashing new rom,
i was try to flash the rom with, CWM and TWRP 2.5.0, and i was try to modified the updater.script, but the results its same,,

FYI, now i'm using CM7.2 rom, and i want to try flash PAC 4.3 rom from this link
and CM10.1 kitkatui from here

and last, sorry for my bad english
