Hi Chianne,
The default number of values in a list is limited to 1000 records.
This is however, controlled by a registry key. To increase this limit, here's what you need to do:
(I'm assuming this a 64-bit machine)
Go to Start > Run > Type 'regedit' (without quotes)
Browse to:
HKEY_CURRENT_USER\Software\Wow6432Node\Business Objects\Suite XI 4.0\Crystal Reports\DatabaseOptions
Create a new key (or folder) called 'LOV' and then on the right-hand side create a new string value called 'MaxRowsetRecords' with a value higher than 1000, perhaps around 20000.
Do this on the HKEY_LOCAL _MACHINE hive as well.
Let me how this goes!
