Are you using the form's "on after start" eep? That evaluates only once, when the form is initially loaded. So if alpha is not 1700 to begin with, the gamma field will never be visible. Nothing will happen if they modify any data in the alpha field.
If it was me, I would make the Gamma field invisible on startup (right-click, hide on startup). Keep your on after start eep so that it will display the field if alpha = 1700. Then I would add basically the same code (with a recalc var at the top) to a "after field exit" eep on the alpha field itself. That way when they exit the alpha field it will reevaluate whether to show or hide. 2 suggestions on syntax: (1) never dot a variable that is left of the = sign. (2) enclose property parameters in quotes: 'FALSE' / 'TRUE' Karen -----Original Message----- From: Daniele Barbieri <[email protected]> To: RBASE-L Mailing List <[email protected]> Sent: Sat, Jun 1, 2013 4:05 am Subject: [RBASE-L] - DB Chech Box in a form Hello Rbase 9.5 (32) In a form I have a DB Edit integer field called Alpha and a DB Check Box called Beta. During the EDIT USING formname if the user enter in the field Alpha (initially empty) the value 1700, the DB Check Box Beta must be visiblile (should magically appear) otherwise NO. In the form variable: vAlpha=Alpha On exit from the field Alpha I've an EEP: RECALC VARIABLES RETURN The component ID for theDB Check Box Beta is GAMMA In the Form the EEP , On After Start: IF .vAlpha = 1700 THEN PROPERTY GAMMA VISIBLE TRUE ELSE PROPERTY GAMMA VISIBLE FALSE ENDIF RETURN But it does not work In fact there should be a refresh of the form based on the value entered in the field Alpha. How can I do this? TIA Daniele Barbieri B.M.B. Informatica
