Sorry, but I'm having trouble following this. eg: var i, x1, x2; x1 = []; x2 = []; x1.push( 1 ); for ( i = 0; i < x1.length; i++ ) x2[i] = x1[i]; console.log( "x1[0] = " + x1[0] +"; x2[0] = " + x2[0] ); Output is: "x1[0] = 1; x2[0] = 1" So I can't really see what the problem is - can you offer code that demonstrates it? -- Denis McMahon, denismfmcmahon@gmail.com
