How to change default view

I tried to mess with the template that has the view posts for last # days, and make it so the last day is always the selected, but I couldn't get it to work anyon tried this?
Btw if you don't understand what I'm saying, let em try to explain

You have a certain number of days as default, say 30, so it will show 30 on the drop down menu on top (or bottom for version 1.1.3) I wanted to have this always show last day, no matter how many days I have chosen!

Anyone?

You will have to change the "ForumJump" function in Global.PHP to make this change.

I thought it was on forumdisplay template, I changed the :

<OPTION value="1" $daysprune1selected>Last day

to


<OPTION selected value="1" $daysprune1selected>Last day


but it doesn't work

Remove all the $xxxxxxxxxxselected variables and place "selected" in the first one.

Thanks a lot Ed worked just fine!
