Help needed: Onclick event linked to repeat region

[cmdrBiggles]

Hi all

I am developing a PHP / MySQL database in Dreamweaver MX.

I have a page which displays: Call_id, date, time, spokeTO, in an HTML table row, which has a repeat region attached to it.

I want the user to either onFocus (on Call_id cell) or onClick event, and then for a seperate HTML table on the same page, to display the conversation field, which is in the same database table as the above fields already mentioned. How is this done?

Thanks
Brian
