Scatter objects addon not working

Question

I was following a tutorial on youtube and trying to make a city in Blender. I used the scatter object mod to scatter buildings around. It worked at first but then I am not happy with the result. So I deleted them and tried to redo them. But when I try to scatter the buildings again, I can't. I pressed f3 selected the scatter object option but when I draw, nothing happens. And when I press enter, an error message popped up. Please help. Here are some photos:

I fixed it and I realized I was a total moron. I didn't know you have to select the plane instead of those buildings when using the scatter object addon.
