The page footer is not dynamic in crystal reports (not up to CR2011), so even if you set the field to 'can grow', if the text/formula or field box is too small to display the data, if will not 'expand' so you can see it in the page footer. Try making the page footer bigger and see if your data appears when given enough space. If it does, then that is the issue and no way to correct this, other than making the page footer big enough to fit the actual data.
