Print not happening on tick (math expression)

Hello you all,

I was just wondering why the following blueprint did not print anything. I am guessing it’s because the exec. flow is never used as an input, but I don’t know how to use that with mathematical expressions. The print of Hello does happen but not the print of the value.

You do not have the execution (white wire) plugged into the print string.

Drag off from the right of green “set running time” node and plug it into the print string.
