Crystal Reports Formula Field 1

[ruan123]

I have created the following formula field - 'Rental Schedule to the Master Rental Agreement between ' + {customers.company_name} +','+ ' Reg. No. '
+ {customers.registration_number} + ' and iVolve Procerument and Rental Partner (Pty) Ltd., Reg. No. 2003/004690/07 dated '
+ToText({asset_register_rentals.created_on}) - but it prints blank every time I preview the report. The database is populated with all the data needed for the formula field, but it stills print blank

Are you sure there isn't a single one of the above fields that is null?
If so, is the field you are using big enough to display all the string?
