Fisrt thx to all for yours answers, I'm updating the mail because in hte last mail I'didn express my self correctly : EXAMPLE page1.php ======================================= <form action="/page2.php?form=yes" method="post">

    $sql_pro ="SELECT Sid FROM table";
    $res_pro = @mysql_query( $sql_pro);
     while ($campo_pro = @mysql_fetch_array($res_pro)) {
             $sid_pro = $campo_pro["Sid"];                  // $sid_pro = 4
             $sid_pro = 'p'.$sid_pro;                     // I'm trying to use the value of         $sid_pro as a VAR name *$sid_pro = p4*                        print "<td ><input name='$sid_pro' type= 'radio'      // Here the Imput Name is a VALUE from Database
            value='AAAA'/>* </td>";              // *name = p4 *
              BLA BLA BLA
      }

page2.php // I Need to access a value from the form witch it's stored in a VAR called $p4 // The Name of the VAR "$p4" It's stored in my database, so How can I convert a database string to a VAR NAME ======================================= $sqlname = "SELECT Sid FROM Table"; $res = mysql_query ($sqlname) ; while ($campo_pro = mysql_fetch_array($res)) {

      $name1 = $campo_pro["Sid"];  // *$name1 = 4*
      $radio = '$'.'p'.$name1 ; // *$radio = $p4
      ----------------------
      Now the Problem
      **How can I get the Value SOLVE_ME  from the submited form ?*
        echo '$radio'; // == $p4 => WRONG i need  AAAA
        // The VALUE of $radio witch is "$p4" is the name of the VAR I need to access, how can I export the VALUE "$p4" AS a VAR Name ?

      }

Small example that might help solve it: $foo = "bar"; $$foo = "Hello World!"; echo $bar; // Prints out Hello World! Greets

Thx for your answer Berry, What if I don't know the value of "$foo " (witch is "bar") so we have this : $foo = "UnKnowName"; $$foo = "Hello World!"; Here is the problem // remember that I dont know the value of $foo echo .'$'.$foo // prints out $UnKnowName but I need to prints out Hello Worlds! so If I don'r know the value of $foo, what can I do tu prints out Hello World! Thx in advance.

echo $$foo Greets
