AE Expressions Invalid Numeric Result Problem
OK I need help … I’m using Dan Ebberts’ Expression below, working in AE CS6.
maxDev = 13; // max deviation in pixels
spd = 30; //speed of oscillation
decay = 1.0; //how fast it slows downt = time – inPoint;
x = scale[0] + maxDev*Math.sin(spd*t)/Math.exp(decay*t);
y = scale[0]*scale[1]/x;
[x,y]AE gives me the following:
After Effects warning: invalid numeric result (divide by zero?)
Expression disabled.Error occurred at line 0.
Please chime in. Urgent, thanks!

I’m guessing that your scale x value is <=0 or that the variable x is evaluating to 0.

I’m not well versed in expressions so what do I do to correct it?

There’s nothing wrong with the expression as you wrote it. It should be applied to a property with 2 dimensions like position or scale.
Line 0 refers to the first line of the expression. Lines in an expression are counted like an array, so 0 is the index of the first item.

There is *nothing* wrong with the script. It works. I’ve just copied and pasted the script in your first post to both position and scale.
To what and how are you trying to apply the scipt?
