Web Development

My user wants to input a list of person identifiers in a box on a web page and then have certain results from the database about the persons identified.
The code block I have at present runs thus:
htp.p ('* Term: '||term);
htp.nl;
htp.p ('In the box, write the identifiers of the students whose status '
|| 'you want to examine, then click below.');
htp.nl;
htp.FormTextArea ('InputList',
'20',
'9',
'left',
'ID = "InputList"
WRAP = "Physical"');
htp.nl;
htp.nl;
htp.anchor (STL_URL || '?term=' || term,
'Click here when you have finished entering the IDs.');

The name of the table is InputList. When I execute the above code, inputting a number of IDs, and test in the procedure referenced by STL_URL, I find InputList to be null. What might I be doing wrong? InputList is defined as a package variable.
