Application.InputBox from Userform

I have a userform that pops up, and from that userform, I would like to click a button that pops up an inputbox (application.inputbox) where I can select cells on the sheet, and then run more code. When the application.inputbox appears, I'm not able to click on any cell because I think the original userform is blocking me from doing so. I've tried changing this userform to modal and modeless, but I'm not having any luck. Can someone please help?

I managed to do that with RefEdit

As I started playing around with this more, I stuck with my application.inputbox solution, and found that by turning screen updating back to True, it now works! I had is set at false at the beginning of the code. I had no idea this would prevent this from working! Thank you both for the quick replies.

In this case, the input box suited my needs better. I hadn't heard of RefEdit before...that could come in handy!
