chased by flies...

hello,

1)I managed to use the chase by character action, by direct actions on items, by It doesn't work when I try to use the action link possibility.( the one above range )
I want my character to be chased by an other character, after taking an item on the ground for example ( it work when I set it on the ''take action'' of the item directly.)

This is what I do :

-Character>called by other action>command and item empty>Current character is chased by "x" ( who is a porn actress ;-)
-range I tried from 20 to 300 ( the item is near to the character )
-Still in character, In the chased action choice, I choose 'Look' executed from the same scene ( action on an objet present on the scene ) and nothing happend.
- I try the Item 'Take' executed, nothing more...

So where am I doing something wrong please? Or if the action doesn't do what I think what is the purpose of this Action field? ( I've red the wiki, but...)

2) Is it possible to be followed on each scene before stop it? Or you have to set it for each scene? ( I want to be followed by flies...Or no...By a sweet pink cloud )
Thank you.
