"Mereka mencoba makan."

Translation: They try to eat.

[Indofreezer]

I was told that "They are trying to eat" is wrong, and I should have written "They is trying to eat." There seems to be a grammar issue in the English.

They try eating is not accepted ..however they are all in the tip box ..

[Kharoda]

Question: would "mencoba" only be used for verbs? Are there different words "trying" on a piece of clothing or "trying" out a new food?
