Newbie Questions..

[MQuser]

Not sure if these are hard to answer or not, I'm very new to making macro's, but interested in learning.

I want to know if, and how, I can check the range to a current target.. then, if its withing a certain range run away and check again, or, if its outside a certain range, cast a certain spell.

Also, how to recast a spell on a target after it wears off. Any help would be appreciated.

I also would love to know what "Couldn't find a comparison operator in '0rget' means.

Thanks.
