Need some insight. Have been staring at this since last night. Placeholder issue

if ($kind == 3){
        #Last record

        $stmt = "SELECT * FROM ( SELECT * FROM users WHERE ? <= ? AND 
+? >= ? ORDER BY ? ASC LIMIT 1 ) sub ORDER BY ? ASC"; 
        
        #example user_id 
#        $stmt = "SELECT * FROM ( SELECT * FROM users WHERE user_id <=
+14999 AND user_id >= 1 ORDER BY user_id DESC LIMIT 1 ) sub ORDER BY u
+ser_id ASC"; #Works fine hard coded

placeholder substitution

    $sth = $dbh->prepare ($stmt) or die "Error Preparing:\n" . $stmt .
+ "\nDBI returned: \n", $dbh->errstr;

    warn("'$searchfield' '$maxrowpointer' '$searchfield' '$minrowpoint
+er' '$searchfield'  '$searchfield'"); #verified correct values in var
+iables at this point
       
    $sth->execute ($searchfield, $maxrowpointer,$searchfield,$minrowpo
+inter, $searchfield, $searchfield) or die "Unable to execute query: "
+ . $sth->errstr;

    my $refresult = $sth->fetchrow_hashref();
    
    my $count = $sth->rows;

This works fine with hard coded vaues instead of placeholders and also testing MySQL directly. count = 1 When running with the placeholders, count = 0

Result with hard code JSON output below
