This question came up when answering tickets today at work. A client says they've been having one singular problem across multiple entries. How should I phrase my response?
"Which entries was this happening on?" or "What entries was this happening on?"
Neither of these sound right. Is the issue tense? i.e.:
"Which entries has this been happening on?"
I'm pretty sure 'which' should be correct because I'm asking for specific entries from a list.
What's the correct option here?
