Custom Variable Calculates, then shows an error message

Hi there, as you can see, my formula calculates, but then it doesn’t work, when I hit refresh or close and reopen the variables table, this is what I get:

PS, I don’t even need variable 1, I was just trying to see if I can get it to work.

Thanks!

Yes, this is because the variables are loaded in the front of the pattern file, just after the measurements are loaded and before any lines have been created. This is why you can’t use the formula wizard to find line lengths and angles or curve. They’re all removed. You can only use measurements and variables that were created before the current variable.
