Screen Controls

When using the programme microsoft excel, there are many drop - down boxes and other screen controls which reduce the likelihood of errors.

Certain controls mean that you can only accept certain entries, they are similar to validation ( mentioned in a previous post) however they are more general. There is a drop-down box called a 'Combo box'. This is where you are given a list to select from to answer the field of information, for example your gender. It will give you the selection of 'Male' or 'Female', and you will click on the one you are!

You can use check boxes to give you a definite choice, which keeps the data being entered into the computer similar, so it is easier to collect and understand.
