|
|
fixeddom - domain, if fixed. |
|
|
|
prevphase - value to assign to form element named "phase" when going back to the previous screen |
|
|
|
cnameelement - name of form element in form on opener page which will receive title of selected course |
|
|
|
cnumelement - name of form element in form on opener page which will receive courseID of selected course |
|
|
|
cdomelement - name of form element in form on opener page which will receive domain of selected course |
|
|
