Correct spacing for words

I have tried without spaces between the first symbol and the colon and with a space but I always seem to get these particles incorrect even with the correct symbols.

I feel it is slightly unfair and a recoding of the text checker would help, but, does anyone know how this should be spaced just so I can get by.

is this from memrise official Japanese course?

If yes the course forum is here. You can post there anything concerning courses Japanese 1 to 7

In regards to your concern, I’m not exactly sure if typing just one of characters would work in the mobile version but in the case of desktops (which I am using), I just type in one of the given items and memrise passes it of as correct. Although this doesn’t resolve the problem of answering with both given items at once, my suggestion is (in my opinion) time saving and more convenient.

(I apologize for my gritty English)

As @Furst_Wasserbrakken said, you probably just need to type one of the answers.

I think that the problem is probably that in the course, they used a Japanese semicolon and you’re using an English one, or vice versa.
