Can “Can you, please, help me” be followed by “as to which”?

Question

Can "Can you, please help me" be followed by "as to which"?

For example,

Thanks for telling me which button on that website I need to click. Well, I clicked on the needed button, but what I got then was a new page written fully in Korean. I don't read in Korean. I am sending a screenshot of that page to you. Can you, please, help me as to which button there I should choose now? Thank you.

Answer 1

The phrase "as to which" is somewhat formal and "dated" (this NGram shows that it's being used less and less). In keeping with that observation, assuming OP stills want to use the phrase, a better way to put it would be...

Can you please enlighten me as to which button...

Note that although the commas aren't exactly incorrect, they're certainly superfluous even with starchy phrasing such as this. A more modern/informal way of asking the question could be, for example...

Can you please tell me which button...

Answer 2

It seems like it would be better if "as to" was replaced by a verb, such as "determine which."

Can you, please, help me determine which button I should choose now?

If "as to which" is used, it should be used more like this, although it's is a pretty cumbersome sentence:

Can you please help me, as to the buttons, which I should choose now?
