Hi,

I have a problem with creating a hash which has a a variable in its name. This works ok for arrays ,eg 

@{"platforms_$site"}

[download]
but not hashes 
%{"platforms_$site"}

Here's my script: 
#!/usr/bin/perl

sub buildconfig;

buildconfig;

foreach $key(keys %sites){
        print "$key\n";
}

sub buildconfig{
        my ($site, $platform, $webserver, $option);

        my %sites = map {$_=>1} @sites;

        # create following variables
        # %sites = BFH, LPR, UAT, TEST
        # @all_platforms and %all_platforms = TEST_MLS, TEST_RST, UAT_
+MLS, UAT_RST ...
        # %platform_TEST = TEST_MLS, TEST_RST, TEST_OPP, TEST_BO ...
        # @all_webservers and %all_webservers = mls001.test, mls002.te
+st, tomcat001.test, tomcat002.test ...
        # %webservers_TEST_MLS = mls001.test, mls002.test
        # %deploy_as = prod, standby, demo
        # %deploy_as_platforms = Prod1, Prod2, UAT, TEST

        my %sites = map {$_=>1} @sites;

        foreach $site (@sites) {

                my %all_platforms = map {$_=>1} @{"platforms_$site"};
                my %{"platforms_$site"} = map {$_=>1} @{"platforms_$si
+te"};

                foreach $platform (keys %{platforms_$site}) {

                        my %all_webservers = map {$_=>1} @{"webservers
+_$platform"};
                        my %{"webservers_$platform"} = map {$_=>1} @{"
+webservers_$platform"};

                }
        }

        my @all_platforms=sort keys(%all_platforms);
        my @all_webservers=sort keys(%all_webservers);

        my %deploy_as = map {$_=>1} @deploy_as;
        my %deploy_as_platforms = map {$_=>1} @deploy_as_platforms;

}

but when it's run I get: 
Can't declare hash dereference in my at ./test.pl line 30, near "} ="
Execution of ./test.pl aborted due to compilation errors.

Could anyone tell me how to fix that please?

Thanks, Ed.
