Have you wanted to have a pageheader section on a Crystal Reports version 9 subreport?  Now you can..

It seems all you have to do is create a formula with:

WhileReadingRecords;
" "

As it's value.  Then Insert a Group pointing to that formula you created and on the options tab, click on "Repeat Group On Each Page" option.  Then simply place your headings in that group and you are good to go.
