APEX

Hello,

I am building an application that handles hardware inventory (APEX 4.0). I have an input page that adds data to two or more tables all at once. The page has two forms on it that point to two separate tables. However when I try to run the page, it fails and returns an error:

ORA-06550: line 1, column 437: PL/SQL: ORA-00904: "ORH_LAST_UPDATE_DATE": invalid identifier ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored
Error Unable to process row of table IDD_ID_DATA.

So far as i can see within the App, that column is not at issue (I am not even doing anything to it and it is nullable). I have looked into the App itself as well as doing some online research but have found nothing helpful...


So my question is this: Is it possible to add to multiple tables from one page? If so how do I do it?

I am new to APEX so any help would be greatly appreciated!
