I have used this in Hello.pl and i have also tried use Hello qw(ReadConfigFile); instead of use Hello; I have multiple functions in the @EXPORT, is there any particular order that i need to follow, i tried lot of sites..i am just not able to figure out why it throws "Undefined subroutine &Hello::ReadConfigFile at c:\test\hello.pl in line 30". Please help..
