Need help - Before i pull my hair out!!!

I believe hoolio meant for the following to be a format example, not an actual line in your code.

 

 

set my_new_string [string map {$find1 $replace1 $find2 $replace2} $original_string]

 

 

In other words, just change the "set newlocation" line as it was originally typed (or, rather, in your current rule replace the line above with the line below) to:

 

 

set newlocation [string map {$find $replace} $location]
