Those are text fields on the template configuration. Just edit the template and you'll see the parameters on the Template Specific tab.
Trying this now, changed it...and will not save and close and keep the changes made.
Any suggestions please?
[EDIT} Strange? Had to go to Maint.....and I checked in and cleared cache and purged..
And it took just one time...but won't let us change it again//
Can this be fixed pleased?
