Setting up multiple conditions in a java script for use with Required Attributes for Condition

need to setup a java script that looks at three attributes - and based on that condition make fields mandatory using the Required Attributes for Condition

I have the following, but it does not appear to be working

dojo.provide("com.example.migrationprodemerg");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");

(function() {
    dojo.declare("com.example.migrationprodemerg", null, {

        matches: function(workItem, configuration) {
          
        var workitem = com.ibm.team.workitem.api.common.WorkItemAttributes;
        var environment = workItem.getValue(workitem.migration.prodnonprod);
    var state = workItem.getvalue(workitem.state);
    var migrationtype = workItem.getValue(workitem.migration.type);

        if (environment == "migration.prodnonprod.literal.l2" && migrationtype == "migration.type.literal.l4" && state != "com.ibm.team.workitem.workflow.nonprod.state.s1") {

           return true;
        }
        else
        {
           return false;
        }
        }
    });
})();

Basically the script is looking for the value of preprod + emergency and a workflow state that is NOT "initial"

Any help gratefully appreciated.
