Question What's wrong with this formula?

[black zero]

CrystalReportViewer1.SelectionFormula = "{solardata.transaction_date} >= CDateTime('" & Tgl_awal.Text & "') And {solardata.transaction_date} <=  CDateTime('" & Tgl_akhir.Text & "')"

Any pointer?

EDIT:
The error is as follow, sorry for pasting the wrong code...

'A Date time is required here. Error in formula selection'

The database just needs to be 'refreshed' from the connection window on the left. The appropriate report object has to be reinserted...
