 Hi,

 I have a list of strings
 (lets say five, "Hi", "bye", "good morning", "Tschau", "Hello world") and I
 want the number of the item I selected (lets say I selected item "good
 morning") In my example it would be 3. How do I get this number so that I
 can pass it to a variable so that I can delete it from a list using a
 removeItem handler. etc.?

set myList to {"hi", "bye", "allo", "au revoir"} set phrase to choose from list myList -- returns a list, eg. {"allo"} set phrase to item 1 of phrase -- a string "allo" repeat with i from 1 to (count myList) if item i of myList is phrase then return i end repeat --> 3

Excellent!

And if speed does not scare you:

on IndexOfItem(theItem, theList)
set od to tid(return)
set theList to return & theList & return
tid(od)
try
-1 + (count paragraphs of (text 1 thru (offset of (return & theItem & return) in theList) of theList))
on error
return 0
end try
end IndexOfItem


which uses:

on tid(x)
	set y to applescript's text item delimiters
	set applescript's text item delimiters to x
	return y
end tid
