Trying to match two tables' data

Hi experts, Here's the scenario: - 3 lines of data is present in a table - 2 lines of detail lines (corresponding to the above) are needed to be entered into a second table Result needed is: table1line1 table1line2 table1line3 (as column headers) table2line1 table2line2 table2line3 (as first line of detail) table2line4 table2line5 table2line6 (as second line of detail) I might be in a wrong approach in accomplising this and would highly appreciate any corrections. In short, column header data is entered into a table, then number of detail lines are obtained (in general, i.e. 2), the display should show 2 lines of input boxes under each header text in the browser for data entry into these detail lines. Clear as mud? Its getting there for me slowly... Thanks in advance. Alp
