Modifying blocks in Forms3

Greetings, I'm the new ORACLE 7 DBA and apps designer for my section. I've been learning how to design in FORMS 3 by following the SQL*FORMS Designer's Tutorial.

I am having a problem with modifying my blocks. How do I go about editting the "Join Condition" from the ITEMS block (figure 3-6 of page 3-11 in the 1992 edition of the tutorial). I've RTFM'ed the tutorial and the FORMS Designer's Reference. No where do they mention how to edit it.

When I do a "(a)Block, (b)Modify" sequence, I am dumped into the spreadtable listing the three blocks (ORDERS, ITEMS, CUSTOMERS). I tabbed through all the fields of ITEMS, I've ZOOMED IN and ZOOMED OUT; yet I can't find the JOIN CONDITION. Did I miss something?

For now I guess I can always delete the block and create a correct version, but shouldn't there be a better way or is there ...??

Thanks,
