Comparing dot product of two vectors

I am having issue with a blueprint script, I am trying to compare the dot product of 2 vectors to 0 to see if the angle between them is < than 90 degrees. I have my dot product from my 2 vectors but how do I calculate the rest, right now I am left with my 2 vector nodes that go into the input of my DOT. Now I am left with a empty dot output and I need to send the dot output to a blue value node.

can you send a picture of your node layout?
