How to call sikuli script within another sikuli script

So I am trying to create a script that will go through and check a GUI for me and then i want to initiate that script within another sikuli script

#gui_checker.sikuli
def genDat(val):
    if val == "y" or val == "yes" or val == "1" or val == 1:
        print "success"
    else:
        print "failure"

---------------------------------------------------------
#valid_checker.sikuli
import gui_checker

gui_checker.genDat(1)

** this is just an example as the contents shouldn't matter much, I'm running into the issue of the second script telling me there is no module named gui_checker, is there some default folder where I need to store my scripts? or a way to route them to each other?

thanks
