Put IDEA scripts together

Hi everybody,
i want to put several IDEA scripts together,  that at the end only with one click i can run all those IDEA scripts. But unfortunately it doesn't work in that way i am trying it:
Sub StartMyScript()
Call FCH()
Call FGL()
End Sub
 
I receive at the second rwo the error message " Sub or Function have been not defined: FCH"
Do you know, if there is another way to do that resp. how can i solve it?
Thanks and regardd, FMLA
