Issues with set beam source/target point

I am trying to get a beam from a character to a mouse point but I have been having issues getting that to work. I am not sure what I am doing wrong but I am new to ue4. I have set target/source method to User set and beam method to Target. The beam starts visible but when I click it disappears.

Figured out my issue. ConvertMouseToWorldSpace gives a normalized world location and direction. So I just had to use that to linetrace.
