Hi, Monica. 

There’s not enough for context regarding your question.  But in auto-layout you can’t set constraints unless you put it on absolute position.

I figured it out. I needed to change the alignment choice in the Auto Layout. When I tried it the first time, the cards were too wide for some reason when it was center alignment versus left and it went straight down but when I tested it with just textboxes with the letters A, B, C, through G, it worked.
