How do I link an activity to my Professional Development Plan?

To link an activity to your PDP whilst in Record my Activities:
1) Select 'Link Activity to Professional Development Plan'. Click inside the box underneath and your current PDP will appear. 
2) Save your recorded activity as per usual. 
Note: To check that it has linked, head to your PDP page and you should see a number in the box labelled 'linked'. The number should reflect how many activities you have linked to your PDP.
