The Target Options

Say someone was going to call up an elemental to do a task for someone, do you think that person's cell phone number, name, and address written on a piece of paper would be an applicable connection if placed in the triangle with the being?

Greetings!
An interesting topic! The nature of "the Link" in Sympathetic Magic, etc. I have a few questions that should be mulled over...
1. Why summon an elemental? (No...I'm serious, this isn't aimed at being flippant with the enquiry)
2. What kind of elemental?
I guess that my questions are pointed at the need for you to provide the 'link' to the subject. Why not just instruct the elemental to the task at hand? Giving an elemental a cell phone number may have some amusing results...the ringer going off at the approach of the elemental, the shorting out of the device or worse yet, the complete malfunctioning of said piece of equipment.
When you call the elemental to do this task it will be you that will provide the target...from your mind. Providing a name and address is not enough, you must give particulars or, at least, a good picture of the target. The 'link' with the target must be compatible with the elemental involved. What would an earth elemental do with a cell phone number? Now a fire or , better yet, an electrical elemental would be better suited to understanding the use of an electrical device...this still doesn't mean that they can/would understand a series of numbers. On top of all this, what is the task you needed it to perform? Different elementals, different tasks.
Well, perhaps our members will have some good advice for you rather than my old ramblings...I like the gist of your question! (IMG:style_emoticons/default/laugh.gif) Maybe another discussion as to why we need to have a 'link' within the use of certain magics? Something to ponder...
