How to check field with javascript

Question

I have a screen where you have the service order states, when that service order is 86, it cannot be changed to 93, as follows in the image below:

If it is changed to 93, when you click save button, it returns an error message

Follow my code below:

if(workOrderStateNew == "93") 
        {           
            var oGrid = scr.getGrid("WorkOrderOperation");
            var rowNum = oGrid.getRowCount();
            var oCOperationState = scr.getObject("COperationState");

            var array = [oGrid,rowNum,oCOperationState];

            if (rowNum > 0)
            {
                for(var i = 1; i <= rowNum; i++)
                {       
                    if(array[2] == "C")
                    {
                        console.log('erro no array 2')
                        gm.showMessage(gm.loadResString("ERRORWORKTYPEESTATE", "PREVENTIVA", workOrderStateNew), MSGICON.IconError);
                        return false;
                    }
                }
            }
        }

It is not running when I click save, even changing to 93 it does not return me the error message when I click save, ja dei console in my condition and the console also does not return anything, which may be?

The function comes from the variable:

                   var workOrderState = selectSentence.selectCommandOneValue1T1W("workOrderState", "WorkOrder", "workOrder", scr.getValue("TBWorkOrder"), true );
