filed in 2003 because the court had previously modified his probated sentence and fine in 2002. Prior to Act 1569 of 1999, a trial court lost subject matter jurisdiction to modify or amend an original sentence once it was put into execution. Gates v. State, 353 Ark. 333, 107 S.W.3d 868 (2003). A sentence is put into execution when the trial court issues a judgment of conviction or a commitment order. Id. A guilty plea, coupled with a fine and probation or a suspended imposition of a sentence, constitutes a conviction. Id. This conviction deprives the trial court of jurisdiction to amend or modify the executed sentence. Id. See also Ark. Code Ann. § 5-4-301 (Repl. 1997). Once a sentence is put into execution, an attempted modification of the original order is erroneous. Gates, supra (<HOLDING>). In Harmon v. State, 317 Ark. 47, 876 S.W.2d
