I am still a little fuzzy on segueing between view controllers. I'm making an app that lets you answer questions to determine your personality type. I'm trying to go from my main menu to another view controller with a table to hold all the questions. My app crashes though when I click my desired button "Take The Test" instead of going to the desired view controller. I don't really want to pass any info to the table view, just segue to the TestViewController.
I set the segue as push when the "Take The Test" is clicked. And it's identifier is "showTestDetail"
