How to make a variable change loop from a min and max?

I followed this wiki tutorial and have it exactly as instructed:

Everything works! I am trying to add on top of that, an ability for the float value that is multiplied with the forward vector to change based on how long the key was held.

I’ve tried float range but only found Random Float in Range from Stream . I’d like the range to increment between two numbers.

Any help will be appreciated. I’ve tried a couple of things such as a custom Timetable and Get input key time down

Im certain I am doing it wrong.
