Hello! I wrote the following trigger to try to create an Issue in JIRA when a case has a status of 'escalated'. However, it's saying that i have a duplicate variable of 'c'. Any ideas? I'm a newbie in apex!

trigger SynchronizeWithJIRAIssue on Case (after update) {
   
   //Identify the Case Type
   String CaseStatus = 'Escalated';
    List<Case> z = [SELECT Id FROM Case WHERE Status=:CaseStatus];
   
    //Identify profile name to be blocked from executing this trigger
    String JIRAAgentProfileName = 'JIRA Agent';
    List<Profile> p = [SELECT Id FROM Profile WHERE Name=:JIRAAgentProfileName];
 
    //Check if specified Profile Name exist or not
    if(!p.isEmpty())
    {
        //Check if current user's profile is catergorized in the blocked profile
        if(UserInfo.getProfileId()!= String.valueOf(p[0].id))
        {
            for (Case c : Trigger.new) {
                 String jiraURL = 'http://jira';
                    String systemId = 'B6DB-9597-179C-LL4Y';
                    String objectType ='Case';
                 String Status = 'Escalated';
                    String projectKey = 'LEV';
                    String issueType = 'Client Issue - Level 1';
                    String objectId = c.id;
                    //Execute the call
                    JIRAConnectorWebserviceCallout.synchronizeWithJIRAIssue(objectId);
            }
        }
    }
}
