New to Scar - Need Help

I need help making a script. It's my first time.

What I need to do (in order):

Code:

Drop Item (1st slot)
Talk to NPC (NPC walks around)
Pick Up Item (The item that was dropped in step 1)
Walk to x/y
Talk to NPC -> Right click(second option) (Doesn't walk around)
Pick Up Item x27
Talk To NPC -> Right click(second option) (Doesn't walk around)
Walk to x/y
Repeat

Any help would be appreciated.
