Entry masks is a way to pre fill a field with a specified format and force the respondent to enter only answers corresponding to the mask that was setup.
- Mask is the formatting mask used to pre-fill the fields. A mask can be composed of following template chars.
9 - Only a numeric character

? - Any character
/ - Date separator
: - Time separator
. - Decimal separator
, - Thousand separator
\ - Escape character
{ - Initial delimiter for repetition of masks
} - Final delimiter for repetition of masks
If we want to respondent to enter only numeric based chars within a field we can use for example a mask of : 9999 which will ask the respondent to enter 4 chars.
- Mask Type allows us to specifiy a specific validation on the mask currently number, date, date / time and time validations are supported.
- Accept Negative Values allows us to specify if we need the negative sign to be shown for numeric values. None wont show any negative sign, Left will show the sign of the left of the mask and right on the right of the mask.
- Display Currency allows us to show a currency symbol next to our mask.
- Valid Charset is the set of chars allowed for the C (custom), A, N chars used within a template.
- Clear Text On Invalid Entry setup the mask to clear its container field if the respondent enters an invalid entry.
- Clear Mask On Lost Focus allows us to clear the mask as soon as the focus on the field is lost.
