不容有失的英文應該點寫?

香港舉辦奧馬項目是不容有失的 :
Hong Kong cannot afford any smallest mistake in holding the Olympics Equestrian Events.

I agree with 意見者： kenjitoru

香港舉辦奧馬項目是不容有失的.
Hong Kong just could not afford any minor mistakes for the Olympic Equestrian Events hosted by Hong Kong.

could not afford any minor mistakes, or
could not allow a single mistake.

但如果我想講"香港舉辦奧馬項目是不容有失的"。應該點寫呢？
Even a minor error can not be afforted while in the Olympic Equestrian Events hosted by Hong Kong.

I think the word "error" is a better description than the word "mistake" while referring to an event.

不容有失的 = even a minor error can not be afforted

hkwaddle解釋很好

It is absolutely not allowed to miss !!!

cannot afford to miss something
afford = 付得起一個代價
miss = 錯失／錯過

啊！原來你講「有失」！咁真係要補充下！

cannot afford to miss something 係指「不容錯失（機會）」

不容「有」失，應該係 cannot afford (to make) any mistake(s)，因為呢個「失」係「失誤」之意，或 there is little room for mistakes / there is precious little margin of error。

「香港舉辦奧馬項目是不容有失的」，我會譯作：

Hong Kong cannot afford (to make) any mistake(s) in holding the Olympic Equestrian Events.

There is little room for mistakes for / precious little margin of error for Hong Kong's organisation of the Olympic Equestrian Events.
