@title Dark Frame Shooter for Meteors
2010/11/16 original script by fudgey
2012/10/18 modified by waterwingz to shoot continuously and record dark frame periocally
@param n Number of Shots
@default n 1000
@param r Raw On/Off (1=On/0=Off)
@default r 1
@param s Shots per Dark Frame
@default s 50
@param t exposure in seconds (0=auto)
@default t 25

Exposure parameter controlled shoot: if argument dark==false, function stores
Tv, Av, Sv from this shot and shoots a real photo. If dark==true, function
overrides camera exposure parameters to match previously stored ones and shoots a
dark frame. Obviously one must always call this function with false before it can be
called with true.

Pasted to file
Renamed file Meteor.lua.txt
Dragged and dropped on
Script File
I then opened script file to chek to see it was there then opened it there so compair copies
Everything seemed fine
Took out SD card
blah blah...
ran script in cam
shoot...
same error
Ive been at this for three days .
having a stroke and losing short term memory sucks ..
did I copy and paste wrong
or is it the new test document i put it on ?
IDK
