You need to be more specific. What script are you trying to use, what setting are you having trouble with ?
Don't forget what the H stands for.

could you suggest one, I have looked at a few and tried but they could be only for other cameras, (don't know if all scripts work with all cameras),,the last one i tried was this one:

@title md split h3

@param a Columns
@default a 8

@param b Rows
@default b 6

@param c Threshold (0-255)
@default c 10

@param d compare Interval (millisecs)
@default d 80

@param e Begin Triggering Delay(secs)
@default e 20

@param f Rows
@default f 1

@param g pix step(speed/accuracy adj)
@default g 8

@param h  reg mode(0-no,1-incl,2-excl)
@default h 2

@param i measure mode(1-Y,0-U,2-V)
@default i 1


if a<1 then let a=1
if b<1 then let b=1
if c<0 then let c=0
if g<1 then let g=1
if f<1 then let f=1

let e=e*1000



print ">[";a;",";b;"] threshold: ";c

let x=30000

for z=0 to 10000

   let t=0

rem              /--/-columns, rows to split picture into
rem              |  |
rem              |  |  measure mode (Y,U,V R,G,B) - U-0, Y-1, V-2, 3-R, 4-G, 5-B

rem              |  |  |  |  |  |  |  |  |  |  |   |    |   parameters- 1-make immediate shoot, 2-log debug information into file. OR-ed values are accepted
rem              |  |  |  |  |  |  |  |  |  |  |   |    |   |  pixels step - speed vs. Accuracy adjustments (1-use every pixel, 2-use every second pixel, etc)
rem              |  |  |  |  |  |  |  |  |  |  |   |    |   |  |  number of milliseconds to wait before begin triggering - can be useful for calibration with "draw_grid" option

md_detect_motion a, b, i, x, d, c, 1, t, h, 1, 1,  a,   f , 0, g, e

if t<1 then goto "zzz"

click "shoot_full"
rem sleep 10
rem release "shoot_full"

:zzz

next z


end

I've had good luck with http://chdk.setepontos.com/index.php/topic,471.0.html which should work on most cameras.

If you had a problem with the script quoted above, you have to describe what you tried to do and what happened for anyone to be able to help you.
Don't forget what the H stands for.
