JavaScript Syntax Error: Missing :after property ID

This is my first time attempting such a form and I have used the Adobe tutorial located at: https://acrobatusers.com/tutorials/change_another_field.  I have managed to replicate the tutorial but not my own document yet.

What I am wanting to do is have my Office Locations (which is a drop down menu) once selected, automatically fill the GLCode field.  I have completed all the steps until step 12 - there with the following syntax, I get an error:

{

var DeptData = {Altona Public Health Office:{ GLCode: "880-1-715521211-46060"}, Boundary Trails Health Centre:{GLCode: "XXX-1-715521211-46060"},Carman Public Health Office:{ GLCode: "XXX-1-715521211-46060"},Elie Public Health Office:{ GLCode: "XXX-1-715521211-46060"},Gladstone Public Health Office: {GLCode: "XXX-1-715521211-46060"},La Broquerie Public Health Office:{ GLCode: "XXX-1-715521211-46060"},La Salle Public Health Office: { GLCode: "XXX-1-715521211-46060"},Lorette Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, MacGregor Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, Montcalm Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, Morris Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, Niverville Public Health Office: {GLCode: "XXX-1-715521211-46060"}, Notre Dame Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, Pilot Mound Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, Portage Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, Rosenort Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, Somerset Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, St. Claude Public Health Office:{ GLCode: "XXX-1-715521211-46060"}, St. Pierre Public Health Office: {GLCode: "XXX-1-715521211-46060"}, Ste.

function SetFieldValues(cOfficeLocation)
{
    // Populate fields with values from the Department Data Object
    this.getField("GLCode").value = DeptData[cOfficeLocation].GLCode
}

The error I get is :  SyntaxError: Missing : after property ID 3: at line 4.  It highlights the function SetFieldValues(cOfficeLocation) line.

Any help here would be greatly appreciated.
