For Each can only iterate over a collection object or an array

The For Each construct can only be used with collections and arrays. This error has the following cause and solution:

• You specified an object that isn't a collection or array as the group part of the For Each syntax.

  Check the spelling of the item over which you want to iterate to make sure it corresponds to a collection or array in scope in this part of your code.

For additional information, select the item in question and press F1 (in Windows) or HELP (on the Macintosh).
