Abnormal issues with pushing data into an array

Mixing "for each" and indices is a bad idea, but that's only part of the problem.  You're going to be pushing something every time the title doesn't match as you go through the loop.  If I'm following what you're trying to do you should do something like:

for i = 0 to m.global.watchList.Count() - 1
   if m.global.watchList[i].title = m.selectedMovie.TITLE then
      m.global.watchList.delete(i)
      exit for
   end if
end for
if i = m.global.watchList.Count() then m.global.watchList.Push(m.selectedMovie)

You could also use a matched flag, but if i is past the end of the watchList at the end of the for loop then it wasn't matched.

A note about your code:  using m.movieArray isn't really accomplishing anything.  Setting it equal to m.global.watchList doesn't create a copy of it, just another reference to the same data.  Take this example:

x = [1,2,3]
y = x
y.delete(1)
print x
print y

It will give:

<Component: roArray> =
[
    1
    3
]
<Component: roArray> =
[
    1
    3
]

Thanks for the explanation. I have tried pushing directly to global variables, but for some reason, it doesn't work. I never thought about the for loop style. I am still trying to figure out what and what I can do with brightscript. And thanks for pointing out the issue with assigning the value of the global array to the movieArray. I'll check this out and get back to you.

P.S: for the line coloured in your code, will "i" work, since it is outside the for loop? I see it was initialized with the for loop.

Thanks a lot!
