How can I only show certain blocks relative to the answer of another question?

Hi there,

I've grasped the basics of Qualtrics but I would like to make my questionnaire better by having questions that are specific to previous answers. My questionnaire is relating to injuries sustained in the past 6 months of CrossFit training. I have one question that asks how many injuries the individual sustained and I would like to have a separate block of questions for each injury. Is this something I am able to do in Qualtrics? If so, how would I go about doing something like this?

I'm completely knew to Qualtrics and I've not really had to use any software for questionnaires before, so any help would be greatly appreciated!

Brad
