Two types of values are possible:
- Constant : is used to enter a fixed value; the value must be entered in the column 'Constant'.
- Entered: the value is entered in the 'Dynamic link' as a function of the usage context.
A parameter is generally valued in the 'Dynamic link':
- From a field in the HTML form,
- From a field of an entity of type session or action,
- From the field of a block (Entity Access to data): in this case, the block ACURRENT is used to read the value.
