You probably want to say something like this:
if( grep { $number4 == $_ } 1, 2 ) {...

[download]
 
use List::Util 'any';
# .........
if( any { $number4 == $_ } 1, 2 ) {...

[download]

Will have Argument "1,2" isn't numeric in numeric eq <==> .... 

Or more simply...
if( $number4 == 1 || $number4 == 2 ) { ...

[download]

Worked without warning, since $number4 is a list. Thanks
