I'm trying to call a form via 'When button press' trigger. I would like the called form to show the current person_id on the calling form. How do I go about doing this. I'm able to open the called form through 'OPEN_FORM' built-in. Any suggestion will be highly appreciated.

Hi Frank

There are two possibilities in Forms to pass a value - in your case the person-id - from the calling form towards the called form :
1. Using a Parameter-List
Before calling the form in your WHEN-BUTTON-PRESSED-Trigger you can use the build-in-function CREATE_PARAMETER_LIST and then fill this list with the function ADD_PARAMETER. When calling the second form you pass the list. In your called form you must create parameters to get the values of the list. Then you can adress the values with those parameters ( eg. :PARAMETER.PERSON_ID ). For more details refer to the Forms-help.
2. Using a global variable
Create the global variable ( eg. GLOBAL.PERSON_ID ) with the build-in-function DEFAULT_VALUE and set the value ( :GLOBAL.PERSON_ID := ... ). Then you open the second form. In this form you can use the global variable, too. Hint : create the same global variable in the PRE-FORM-Trigger of the called Form using DEFAULT_VALUE. This will not overwrite the passed value, but enables the second form to run "solo" as well.

Hope this helps ... Enno
