< not working

Ok, so I posted this question in blueprints thinking I was doing something wrong but turns out it might actually be a bug.

So in the picture Mana = 1 and Healmana = 0.1.

The problem was that mana would not go below 0.1

I changed the values to mana = 100 and healmana = 10 and it works perfectly then to get the progress bar to work I divided mana by 100 on the progress bar function.

But the bug I guess is < is not working with the first values?

IF I have done something wrong I would like to know because I spent hours figuring it out lol.

Many thanks
