So I have this script here in which I am trying to call a custom handler called “addReminder”
	tell application "Safari"
		set tabname to get name of current tab of window 1
		set taburl to get URL of current tab of window 1
		addReminder(tabname, taburl )		
	end tell
However I get this error “error “Safari got an error: Can’t continue addReminder.” number -1708”
So my question is how can I call one of my custom handlers while with an Tell block?
