Hi Ambellica! It is completely correct, but you have to remove the tick, unless it's a question, for example: Cuando hago mi maleta, nunca sé qué poner dentro (When I do my suitcase, I never know what to put inside). ¿Cuándo hago mi maleta? (When do I do my suitcase?) I sincerely hope this helps.

It would be only "Cuando" without the tick.

Is correct!
