When I run the crystal report, getting following alert-error message.

 

'The String is non-numeric'

 

and then open the window of following script of Crystal report.

 

 

not({member.division} in ['99','98','97','96','95']) and
Date (ToNumber ( Left ( {?StartDate}, 4 ) ) , ToNumber ( Mid ({?StartDate},5 ,2 )), ToNumber ( Mid ({?StartDate}, 7,2 ))) = {payhist.STARTDATE} and
{@Include the benefit in the report?} and
{workstat.BENELIG} = True and
(
( {workstat.BENELIG} = True and {@Coverage amount} > 0 )
or
{@Deduction amount - absolute value} > 0
)

 

Can you please help. Thanks.
