MS Project Pro 2016 Macro Help

I'm quite new to VBA and am struggling to write a macro that will copy data from a custom Resource field to a custom Task field. Specifically, I want TaskField.Number13 to equal ResourceField.Number1 based on the Resource Name assigned to a task.

This is what I have so far...

Code:

---

Sub CopyResourceSkillLevel()
' Copy Resource Skill Level from Resource Sheet to Task Sheet
    Dim res As Resource
    For Each res In ActiveProject.Resources
    For Each asn In res.Assignments
        ResourceField.Number1
    Next asn
    Next res
    ' transfer data to show in the Task Usage view
    Dim tsk As Task
    For Each tsk In ActiveProject.Tasks
    For Each asn In tsk.TaskField
        ' use only ONE of the following:
        ' to show the task's value use
        ' asn.Text2 = tsk.Text2
        ' to show the resource's value use
        res.ResourceField.Name = tsk.TaskField = "Resource Names"
        tsk.TaskField.Number13 = res.ResourceField.Number1
    Next asn
    Next tsk
End Sub

Any suggestions on how to achieve what I'm trying to do? I'm really hoping to not have to do it manually for each task.
