The clue is:
	Global symbol "$words1" requires explicit package name at - line 4.
Which is: 
	my $words1count=$words1;

$words1 hasn't been mentioned anywhere, you need to do:
	my $words1count = @words1;
And that enables the rest of the program to work:
words1
------
There are 5 elements  in list @words1
abc:1:2:3:def
1
2
