"Please don't look at the notebook."

Translation: ノートを見ないでください。

[3Spanish5Me]

Said Light to the rest of the world.

[Pikachu025]

Deathnote reference, hmmmmm

[Achimx]

Difference between で and て ?

[KeithWong9]

Memorize it - ないでください is a fixed phrase. We don't say なくてください.

[LiamOng]

Could you also say 'ノートお見なくて下さい'?

[wairanmax]

Don't use the て form when making a negative request with kudasai, use a negative verb + で + ください

[Lloyd76445]

Nooto wo mi nai de kudasai.

[AnCatDubh]

Why is 下さい with a kanji rejected?

[hollt693]

Maybe that should be accepted, but it's usually written in kana alone.

[Ken5685]

I don't know how you got character input, but all hiragana is more common

[Ken91523]

i put a 私 at the beginning and that was apparently wrong

[Albur_Godwin]

Indeed: the sentence is not referring to the speaker, it is only a command.
