Validate one field or the other is filled in transition

Question

I tried to check the filling of fields by following way:

if (cfValues['Номер письма'].value !='' || cfValues['Другой способ извещения'].value !='') {true}

but this does not work. Any suggestions?

It works!

cfValues['Номер письма']!=null || cfValues['Другой способ извещения']!=null

Thank to everybody :)
