Sorry, I really do define var1 right at the top of script A. Like this (and
note the more accurate error handler structure):
Script A:
global var1
set var1 to 0
try
repeat with i from 1 to 100
set var1 to var1 + 1
-- do stuff
end repeat
set f to load script alias "path:to:script B"
tell f to set var2 to someHandler()
on error errMsg number errNum
my ErrorHandler(errMsg)
end try
on ErrorHandler(errMsg, errNum)
display dialog errMsg
set g to load script alias "path:to:script C"
tell g to set var3 to anotherHandler(var1)
end try

How can it not be defined? I'm wondering if script B, which indeed does not

It's going to be very hard to replicate the original error since I don't

know what it is. But var1 is certainly always defined in script A and is

Does anyone know what's going on?
