My question is twofold. I have got three fields(text boxes) that make up a total.

Firstly. Is it good practice to store the total in a field in a table when it can be calculated and placed on the form in a text box? I seem to recall that I have read somewhere in FPD 2.6 manuals that a calculated field should never be stored.

Secondly. In the Developers Guide p234 (VFP 5.0) it states that I can create a new property to store a value and a method to hold the code for the property. I've tried to create a new property called myTotal (Form menu, New Property), but it does not show on the Properties Form1 of my form as in the picture on p235. Anybody got any idea what I am doing wrong and how do I rectify the problem.

Thanks in advance.

Petrus.
