I am trying to set up price levels for my items in Reckon Accounts Accounting 2014 Small Business Edition.
I did think this would be straight forward but when I went to set them up I do not have a checkbox for use price levels (unless I am looking in the wrong place) but the help sent me to 'Edit', 'Preferences', 'Sales and Customers' and check the box 'Use Price Levels' but I don't have one:-

I guess there is somewhere else in my setup that I will need to edit but I cannot find where it is.
I would be grateful for any help regarding this.
