Debugging an expression (square root trouble?)
I have a complex expression that I will be applying to hundreds of layers, and there is a bug. Through a bit of experimenting, I’ve deduced that knowing how to fix the bug in the following expression would be sufficient for my needs:
x0 = 1; y0 = 2; r1 = Math.sqrt((745 – x0)*(745 – x0) + (660 – y0)*(660 – y0)); x = r1 + x0; y =r1 + y0; [x,y]
Any help would be appreciated!

Somehow you ended up with em dashes instead of minus signs. Try it this way:
r1 = Math.sqrt((745 – x0)*(745 – x0) + (660 – y0)*(660 – y0));

Thanks so much, Dan. Initially I had written the expression out in word, then copied it into AE. I tried trying the expression directly into AE, using the default “-” on my keyboard, and the expression worked. I might not have tried that without your feedback, so thanks again.
