Using a formselectoption value before form has been submitted

Question

Hello experts,
I have written a web application, generating HTML via PL/SQL.
Is there a way to check the value that was selected in a formselectopen statement? If the person filling out the form selects ‘Yes’, the formsubmit button should say “Submit”. If they select ‘No’, the formsubmit button should say “Next”.
I’ve tried the code below, and my package won't compile. I get this error message: PLS-00201: identifier 'P_HOME_SCHOOLED' must be declared. Here's the code. Thanks in advance for your help.

HTP.formopen ('mypackage.p_create_detail', cattributes => 'name=p_detl');
HTP.tableopen;
HTP.tablerowopen;
HTP.tabledata ('<b>Home-schooled?</b>');
HTP.PRINT ('<td>');
HTP.formselectopen ('p_home_schooled');
twbkwbis.p_formselectoption ('Please Select', NULL, 'SELECTED');
twbkwbis.p_formselectoption ('Yes', 'Y');
twbkwbis.p_formselectoption ('No', 'N');
HTP.formselectclose;
HTP.PRINT ('</td>');
HTP.tablerowclose;
HTP.tableclose;
IF p_home_schooled = ‘Y’ THEN
HTP.formsubmit (cvalue => 'Submit');
ELSE
HTP.formsubmit (cvalue => 'Next');
END IF;
HTP.formclose;
Here's the version information:

Thanks for your reply, Shankar.
I don't think that I need to define p_home_schooled as a variable, since it's defined in the formselectopen statement, and the value that the user selects is successfully being passed to mypackage.p_create_detail. The program compiles if I replace the if statement with just this line:
HTP.formsubmit (cvalue => 'Submit');
What I need to do is to somehow get the value that the user selected (Y or N) and based on that value, display either a Submit or a Next button.
Thankis for your help.
