## Calling a User Form

| LogiView manages user forms centrally. Thereby it is possible to call each user form from any decision table.
| ### Syntax:
| ${FORM_NAME}
{FORM_NAME} | Name of a user form
| In order to ensure correct processing of a user form it is neccessary to define decision table variables or constants with the same name (calculation fields in terms of the DataView definition) for all fields contained in the form (as DT-, Logic Model, or System variables or constants).
| In terms of a condition the call of a user form is always true.
| Please note that the full name of the form is composed of the entered name and the prefix "LVF_".
| ### Example:
| Form call in a decision table $BO_INP
| Result:
| The form LVF_BO_INP is called.
