Your quotes aren't quite right. Change to:

$( '#attachPoForm_'+id).show();

This isn't a "jQuery variable", it's just simple Javascript variable and string concatenation.

Your selector is looking for an element with an id of (literally) #attachPoForm_"+id+", I think you mean:

$( '#attachPoForm_'+id).show();

Try this

$( ".attachPo" ).click(function() {
    var id = this.id
    $( '#attachPoForm_'+id).show();  // id name = attachPoForm_59
    //                ^^^^ Fixed the quotes here 
});

 $( ".attachPo" ).click(function() {
       $( '#attachPoForm_'+ $(this).attr('id')).show();  //set  id name = attachPoForm_59
    });

A mistake at

    $( '#attachPoForm_"+id+"').show();  // id name = attachPoForm_59

should be

    $( '#attachPoForm_'+id+'').show();  // id name = attachPoForm_59

Try to use this.id like,

$( ".attachPo" ).click(function() {
    var id=this.id;
    alert(id);
    $("#attachPoForm_"+id).show();  // id name = attachPoForm_59
});
