Now, basicaly I have a program i can add more releveant code if necessary, this program lets me depending on the 5 values that are sent to it show the blog entries for up to 5 days, 4, days, 3 days, 2 days, or just one day (which is default)

I want to adjust this so that it shows the last 10 enties, last 20 entries, last 30 entries or last 40 entries, instead of show them on a daily basis.

So can anyone suggest whay I have to change for this script to work?

thanks

In the SQL query simply use

LIMIT 0,10
LIMIT 0,20
LIMIT 0,30
LIMIT 0,40

what exactly would i change in the php code?

depedning on the var it changed

ie. index.php?history=1
index.php?history=2

so where on the code would i modify?

thanks
