Also the split statements you've used will cause the spaces between the
commas and the "item" strings to be preserved in the resulting arrays which
is probably not the desired effect.

ruby-1.9.2-p0 :001 > globalarray = globalcampaigns.split(",")
 => ["item1", " item2", " item3", " item4", " item5"]


To get around this, pass a regular expression with optional leading and
trailing whitespace as the parameter to split.

ruby-1.9.2-p0 :002 > globalarray = globalcampaigns.split(/\s*,\s*/)
 => ["item1", "item2", "item3", "item4", "item5"]
