After a review of the record on appeal we find that the trial judge did not abuse his discretion by entering a final judgment based upon a default by the defendants. There has been no showing of mistake, inadvertence, surprise or excusable neglect by defendants as required by RCP 1.540 (b), 31 F.S.A. that would compel this court to set aside the final judgment.

Accordingly, the final .judgment is affirmed.

Affirmed.
