Simple time expression for X axis only

I need to make a simple expression for the Offset Turbulence parameter on the Fractal Noise effect, x axis only.

 

The expression I want to use is: time*100

 

Normally I can just go to an image's Position, r-click and choose Separate Dimensions, and then just apply the expression only to the x postion but I can't separate the dimensions of the Fractal Noise's Offset Turbulence.

 

How can I apply the time*100 expression to the X axis only of the Offset Turbulence paramenter in the Fractal Noise effect?

Thank you!

You just need to create an array.

[time * 60, value[1]]

When writing expressions always look at the property. If there is more than one value, except for rotation which has revolutions and degrees which is actually only one value, then the array can be 2, 3, or 4 values. 3D layers have 3, Color has 4 (R, G, B, A) with a range of 0 to 1. 3D layers have 3 values for anchor point, position, and scale and they are defined like this. [value[0], value[1], value[2]]

 

I hope that helps.
