yes, unless you call other routines, the execution might jump

no
you must have overseen the new call.
open your script in a script window.
click into the script text
Select EDIT->FIND->TEXT
enter goMulti in the "find" line
check "all casts"
press FIND again and again until you find something like Howdy said
(goMulti=new ect)
This way you should find it
Another possibilty might be that goMulti has been declared in another
movie and the movie you are talking about is a miaw or being played by
the "main" movie. Then you should find it there
