Hi Julia,
You can use javascript and/or server-side validation:
javascript:
isNaN(field.value); //verify if the value 'is not a number'
server side: (there are many ways)
try {
Double.parseDouble(getField());
} catch (NumberFormatException nfe) {
// if this exception is thrown the value of the field is not a number
}
