AppleScript : variable is not defined

Question

I have a variable extracted from a plist file (that the best way I figure out for passing variable from one script to a another)

It's work fine, if I do a random "display notification var1" I have the correct result.

However if I want to pass the variable in a fonction ex.

set var1 to ""
set the plistfile_path to "~/Desktop/_DATA.plist"

tell application "System Events"
    set p_list to property list file (plistfile_path)
    -- read the plist data

    set var1 to value of property list item "DSID" of p_list as text
end tell

[...]

on makeStatusBar()
    set bar to current application's NSStatusBar's systemStatusBar

    set StatusItem to bar's statusItemWithLength:-1.0

    -- set up the initial NSStatusBars title
    StatusItem's setTitle:var1
    -- set up the initial NSMenu of the statusbar
    set newMenu to current application's NSMenu's alloc()'s initWithTitle:"Custom"

    newMenu's setDelegate:me (*
    Requied delegation for when the Status bar Menu is clicked  the menu will use the delegates method (menuNeedsUpdate:(menu)) to run dynamically update.


    *)

    StatusItem's setMenu:newMenu

end makeStatusBar

I have this error

"The variable var1 is not defined. The variable var1 is not defined. (-2753)"

How can I fix this? thank you in advance.

Answer 1

var1 is in local scope. Declare it as property:

property var1 : ""

Alternatively declare it as global:

global var1
set var1 to ""

The other variable theDSIDFromPlist doesn't appear in the code.
