Help translating short sentence from Japanese to English?

Question:

having trouble with this sentence from a 読み物：
“have a nice day" というのは日本語でなんと言うか、と聞かれるのも困る。

I'm think it means: how do you say 'have a nice day" in Japanese is also a question trouble(?)

Answer:

Your answer is almost correct. According to the context, "困る“　can mean either "an embarrassing (question)" or "(a question) hard to (answer)" .
