Dinesh Posted June 23, 2019 Report Share Posted June 23, 2019 Hello, I am trying to extract variables from the P3DV4 and store them on a CSV. The given example works great for me. But when I try to write the code myself it doesn't work. Moreover, when I just copy paste the code with varied parameters I still get some error. I have attached the error below along with the code. Please do help me out.

After a quick look the code above "seems" to be good - not tested. It looks like your text editor is making the error, introducing an illegal character. (line1) Make sure your text editor is in english & ANSI or UTF-8 encoding. 4 hours ago, Dinesh said: 886422 *** LUA Error: G:\P3Dv4\New folder\Modules\parameters test1.lua:1: unexpected symbol near 'ï' Roman Link to comment Share on other sites More sharing options...
Dinesh Posted June 23, 2019 Author Report Share Posted June 23, 2019 Can you suggest any good text editor for LUA scripting? currently, I am using notepad and store it with UTF8 encoding Link to comment Share on other sites More sharing options...
