For each OPTION you wish to use you must specify a Name and Value
The Name is what will appear in the drop-down list when viewed on the phone
The Value is what will be stored in the database when this option is selected for entry to a select one element.
We use these two values because in some cases you may not want to store what is selected by a user as the value in a database. For example, if you had 10 options you wanted to define (eg a list of colours) you may want to store integer values for your list of 10 rather than the name of the colour.
To specify further options simply click the 'Add Option' button and this will add a new option where you can fill in the name and value. So back to our 'Male or Female?' question. In this case we are going to define two options 'Male' and 'Female' Having entered 'Male' in both the option name and value, we can now click 'Add option' and fill in the details for the 'Female' option, as in the following figure.
For this question, we might want to chart the data and so we click the 'Chartable' check box (and we've chosen a pie chart) and also the 'required' option as, in theory, it should always be possible to answer this question.
