Bug 5391 - can't add multiples to batch

Bug 5391 - can't add multiples to batch

This was due to the use of an OR which seems to have caused the
param method to be called in a scalar context thus returning only
the first of multiple repeated cgi params.

This patch retains the intent of the OR by replacing it with a
conditional.
