Question Just a short question in Perl
Greetings there foreign forum visitors. I am completely new to programming, in fact i have only started today, but i am a fast learner. I decided to undertake Perl and i wrote a simple program that has 2 main loops , each of which are supposed to take an input value number from the user, and check if it fits the requirements (being between 1 and 100 ), and then it will multiply them and find the module. Pretty straight forward. This is what i wrote:

Code:
use strict;

print "this is just a test", "\n";
MAIN_LOOP1:
print "please enter the first number between 1 and 100", "\n";
my $X = <>;
chomp($X);
for $X (1 .. 100)
{
	print "now onto the next step", "\n";
	else
	{
		print " the number does not meet the above requirment", "\n";
		next MAIN_LOOP1;
	}
}
MAIN_LOOP2:
print "please enter the second number between 1 and 100", "\n";
my $Y = <>;
chomp($Y);
for $Y (1 .. 100)
{
	print "now onto the calculations", "\n";
	else
	{
		print " the number does not meet the above requirment", "\n";
		next MAIN_LOOP2;
	}
}
print $X, " * ", $Y, " = ", ($X*$Y), "\n";
print "Finding the module" . "\n";
print $X, " % ", $Y, " = ", ($X%$Y), "\n";
print "Terminate", "\n";


And when i try to execute it in my perl cmd, i get the following errors.

Code:
c:\Strawberry\SCRIPTS>perl new.pl
syntax error at new.pl line 11, near "else"
syntax error at new.pl line 16, near "}"
syntax error at new.pl line 24, near "else"
syntax error at new.pl line 29, near "}"
Execution of new.pl aborted due to compilation errors.

Now i have searched over the forums a bit and i seemed to find other users with the same problem but none of the answers i found ultimately changed the outcome, so i thought to post my thread.

NOTE: This is my first ever program so no making fun. Also if anyone has any better syntax or recommendations, they r more than welcome.

perl::critic::policy::inputoutput::requirebracedfilehandlewithpr

Perl::Critic::Policy::InputOutput::RequireBracedFileHandUsertContributed PerPerl::Critic::Policy::InputOutput::RequireBracedFileHandleWithPrint(3)

NAME

       Perl::Critic::Policy::InputOutput::RequireBracedFileHandleWithPrint - Write "print {$FH} $foo, $bar;" instead of "print $FH $foo, $bar;".

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       The "print" and "printf" functions have a unique syntax that supports an optional file handle argument.	Conway suggests wrapping this
       argument in braces to make it visually stand out from the other arguments.  When you put braces around any of the special package-level
       file handles like "STDOUT", "STDERR", and "DATA", you must the '*' sigil or else it won't compile under "use strict 'subs'".

	 print $FH   "Mary had a little lamb
";  #not ok
	 print {$FH} "Mary had a little lamb
";  #ok

	 print	 STDERR   $foo, $bar, $baz;  #not ok
	 print	{STDERR}  $foo, $bar, $baz;  #won't compile under 'strict'
	 print {*STDERR}  $foo, $bar, $baz;  #perfect!

CONFIGURATION

       This Policy is not configurable except for the standard options.
