I'm trying to remove a text string using the "~s///g" syntax from a list of directory paths which is stored in an array, and it's just not working.

I googled this topic for hours, double-checked my syntax over and over, but I just don't understand what I'm doing wrong.

Before I go down the road of using "substr" & "index", I'd like to see if anyone has any input/thoughts/suggestions on this.

# List of Directories within ACE Directory Template
my @ACETmpltDirs = ("./dataoper/stagecdm.aceprd/stagepgms");
my $ACETmpltDir;

# ACE Environment
my $ACEEnvironment = "aceprd";

# Deal with each Directory within ACE Directory Template
foreach $ACETmpltDir (@ACETmpltDirs) {
   if (index($ACETmpltDir,".$ACEEnvironment") == -1) {
      print "no env: $ACETmpltDir";
   }
   elsif (index($ACETmpltDir,".$ACEEnvironment") != -1) {
      print "env    : $ACEEnvironment\n";
      print "w/ env : $ACETmpltDir\n";
      $ACETmpltDir = ~s/$ACEEnvironment//g;
      print "w/o env: $ACETmpltDir\n";
   }
}

The result makes no sense to me, and I cannot figure out what I'm doing wrong. 
env    : aceprd
w/ env : ./dataoper/stagecdm.aceprd/stagepgms
Use of uninitialized value in substitution (s///) at ./acedirs_build l
+ine 192.
w/o env: 18446744073709551615

Line 192 is "$ACETmpltDir = ~s/$ACEEnvironment//g;".

Any help/insight would be very much appreciated!
