Question: "I did the values questionnaire however I ended it a bit short and didn't complete the last prioritisation of the last two (of three) lists. I clicked 'next' by accident. I'm not sure how much this will affect the overall score. Can someone advise on what is the best course of action?"
Not ranking the values on the last page won't make much difference to the overall pattern of your values. The last page only lists your lowest priority values. By not ranking them they are all given an equal low rank.
The two pages before the last enable you to rank your highest priority values. Ranking the values on those pages is important for your inventory of values to be useful. If you wish, you can always log back on with the UserID and Password you registered. You will find all your responses have been saved, so you can quickly go through the inventory to get to the last three pages where you will have to undertake the ranking again. No charge is made for re-taking the inventory in situations such as this.
