Thanks for the info.
Here's what I am doing.
-Copying script from Wiki to TextEdit(Mac), saving as rtf file called mint.lua
-Copying this file to Scripts folder on memory card.
-Load script from file..
-Only 2 settings are shown Shooting interval and sec.... I changed to 5 secs then
press back and menu to exit to main camera screen.
Press shutter and line 1 error is shown.
Also tried transferring file to pc in notepad.
Unable to create extension .lua and save file to it..so I created a file called
mint.lua.txt first...copied script to it ....then changed extension to mint.lua and
transferred to memory card.
Still getting line 1 error.
Script is exactly as you said with correct spaces etc.
