Getting the correct path of an alias

So I have the path of an alias folder in a variable. How can I get the actual file path using this piece of info? I thought that using "Get File Attribute" would help me here but no dice. I don't want to open the finder for this operation. The goal is to have a KM watchfolder where I drop aliases of other folders into it and affect the subfolders of those original directories. Any help would be greatly appreciated!
