I found 4 problems with your code:
2 syntax errors
1 logical error
1 formatting for this site error

syntax error #1:
you have
push @{$p2i{sp}}, $ipr;  # $ missing for key reference

[download]
when you should have
push @{$p2i{$sp}}, $ipr;

[download]

syntax error #2:
you have
print "$key\t$p2i{$key}\n";

[download]
when you should have
print "$key\t@ {$p2i{$key} }\n";  # need @ to dereference array

[download]

logical error #1:
your use of uc() for key lookups will return nothing because the hash keys, as entered from the text file, are all lowercase (at least in the sample you provided).

formatting error #1:
you have
if (exists $p2i{$user}) {
        print "$user is in the hash. \n";if (exists $p2i{$user}) {
        print "$user is in the hash. \n";

[download]
when you should have
if (exists $p2i{$user}) {
        print "$user is in the hash. \n";

[download]


I corrected the above and the code ran fine

hope this helps,
