Hi,
how do you load that next level? a float field by itself doesn't load levels, so you must have some logic ( good or bad

that leads to a state where you actually use the load level action.
so, first, what's your logic between the float value and the level loading? a float is not a level, you can either use ints or strings, but not float, so I am bit unsure on where is the link between your float and loading levels.
bye,
Jean
