Also i just put disable display on yes on the script settings, i dont understand the other day and night things?(or i havent seen them)
My mistake - I was looking at a different script. You've answered my actual question here. Thanks.
It switches the screen off takes a picture and then previews the picture(so switching on the display) i tried to disable review but it didnt make any difference...
When you say "disable review", did you mean setting the Shot Review
setting in the Canon Menu (i.e. not a CHDK menu) to Off? That's the Canon setting that determines how long a copy of your most recent image taken is displayed after the shot completes. It needs to be set to Off for the script to be able to disable the LCD.
You can test that in normal shooting mode (no CHDK loaded). When you take a photo, the LCD should not show you the most recent image. It should just stay in picture taking mode.
If that works as expected, we can try a little test script to see if it's related to the CHDK port for your SX240hs.
Also how do a get the pictures to save on the second partition???
The SX240hs was released in 2012 and thus does not need to use - or support the use of - dual partitions on your SD card.
