Using UserForm to collect user input

I have a series of ~50 questions that I want to iterate through having primarily a Yes No response. In my Userform, I have a label I am populating with each question sequentially and want to cause my program to pause until the user clicks a Yes or No command button. I few questions, if answered Yes, have a follow up question to answer as well and I am using checkboxes for these. How do I program my UserForm to pause until a response is clicked for each question? My code is significantly long so I did not paste it in but can if it helps. Thanks.

Are you using a YES/NO popup message box? Or just a YES/NO command button on the userform? If you use a popup YES/NO, then the code will pause and wait for click.
