[SOLVED]conky-lua-nv help?

Hi,

I just installed conky-lua-nv from the aur, trying to get lua rings working, but I get this error when I attempt to run it:

Conky: /home/dan/.conky_rings: 2: no such configuration: 'lua_load'
Conky: /home/dan/.conky_rings: 3: no such configuration: 'lua_draw_hook_pre'

Output of conky -v is:

 conky -v

my test conkyrc, I'll fix it up once I work out how to get it to start

Ring Meters by londonali1010 (2009)

This script draws percentage meters as rings. It is fully customisable; all options are described in the script.

IMPORTANT: if you are using the 'cpu' function, it will cause a segmentation fault if it tries to draw a ring straight away. The if statement on line 129 uses a delay to make sure that this doesn't happen. It calculates the length of the delay by the number of updates since Conky started. Generally, a value of 5s is long enough, so if you update Conky every 1s, use update_num>5 in that if statement (the default). If you only update Conky every 2s, you should change it to update_num>3; conversely if you update Conky every 0.5s, you should use update_num>10. ALSO, if you change your Conky, is it best to use "killall conky; conky" to update it, otherwise the update_num will not be reset and you will get an error.

To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):
    lua_load ~/scripts/rings.lua
    lua_draw_hook_pre ring_stats

Are you sure there were no errors while compiling and installing the package?

@Andrwe- Thanks, I had to remove conky and reinstall. Now I just have to tweak it.
