Connecting blueprint interface to get text size

I have a variable called “totalTime” from my level blueprint. I want to have this load dynamically into my HUD blueprint. I can print out “totalTime” in my level blueprint, and I can manually set the time in the HUD, but I just can’t figure out how to connect these two nodes together (TotalTime blueprint interface and Get Text Size in HUD). See below:

How can I wire this? (Whatever I use for the Get Text Size I will also wire to Draw Text).

Thanks in advance,
