Hi, I have 2 questions:<br/><br/>Is there anything wrong with the following:<br/><br/><i>I have a meeting with him at 2pm but he said he'll be busy then. Is it still on?</i><br/><br/>Which preposition should I use for the sentence below?<br/><br/><i>The match is on for/on Friday</i><br/></br>Thanks.
