some one please help me

i need to know how can i make a script or how can i edit a script pleas i realy need help

Then you realy need to ask a specific question. Btw: what do you mean by a script? Jass or a trigger?

edit - convert to custom text in trigger rditor or insert custom script int TFT editor.

i mean in the trigger i want to place archimonde in my map but he dont do nothing he just standing in his base and i got one of the single player scripts and i want to edit that script and i dont know how

Call it a trigger, if you don't I will be forced to kill you.

When do you want him to spawn?

You need to do this:
1. Create a Region (This is done trough the Region layer), name it after you've created it.
2. Go in to your trigger editor, create a new trigger.
3. Set an event, this is when your trigger is going to be set off, when something happens. Let's say you want it to be created after 60 seconds of playing.

Events:
Elapsed game time is 60 seconds
Actions:
Create 1 Archimonde for Player X at YourRegion facing (default building angle)

That's how your trigger should look, you need a region to spawn in. And you need to know who you want to own the new unit, Player 1, Player 2? And so on...

it seems like you are pretty new to triggers, it might be helpful to read the tutorials in the Tutorial section of this very forum.

Specifically the Triggering tutorials

no you didn't understand i dont want him to spawn i want him to attack he just standing in his base

You could use this trigger
Event-Unit-Unit enters region
Condition-Unit-unit type equal to archimonde
action-Issue order targeting a point(or unit)

the order must be Attack-Move

Yea what he said. Cause as soon as you figure out this one you'll be right back here asking how to make the next trigger. Read...experiment....then ask.
