Whats wrong with this list of servers in my bash script?

I am writing a simple bash script (checkServs.sh) that will ssh into a
list of servers and perform a health check on them.
I keep getting errors on the following line:
SERVERS=(blah1.example.com blah2.example.com blah3.example.com
blah4.example.com)
Error is:
checkServs.sh: 3: checkServs.sh: Syntax error: "(" unexpected
I've checked online examples and this seems correct, isn't it? Thanks in
advance!
