hello friends ,
i m new with crystal reports,and i m facing a problem while creating the dynamic parameters optional.

this is the formula i m using

(
({field} ={?Parm1} OR ({?parm1}) ="")
AND ( {field1} = {?parm2} OR {?parm2} = "")
AND ({field2} = {?parm3} OR {?parm3} = "")
AND ({field3} = {?parm4} OR {?parm4} = "")
)

the error it gives when i pass a null value i.e "..." is Error: The value is not valid..

but this formula is working fine with static parameters..

I m using Crystal report X1 release 2
please help me out with this
