Issue with the Lerp node

Hi Guys, i’ve this issue with the lerp node, i want to lerp from a float A to a float B, i readed on the forum that i should use the timeline node so i write this

The problem is that the result float is wrong, like a random sum…
What i’m doing wrong ? The timeline is setting in this way: Lenght 1, point1(Time0 Value0), point 2(Time1 Value1).

That’s because you are changing Dollars value as you interpolate between that and B. You should make another variable which wont update until the timeline finishes(i.e. another float variable named Dollars_2 which you set to the value of Dollars right before you start the timeline and use that as A and to Add to Car Grill… variable.)

Thanks for the reply
