Hi Still having problems - found the place to insert but when I use "Test" it comes up with "the expression at the position . is not a recognised function". So where exactly should it be put? I have used various genealogical programmes but never had to write my own expressions. The use of "circa" is a recognised way of expressing "about - roughly" which is great when taking ages from marriage certificates as a starting point.
