"` (  pid int not null auto_increment,   primary key(pid),  name char(15))";  if (mysqli_query($con,$sql))  {  echo "table created";   }   else  {   echo "did not create table";  }      mysqli_close($con);

above page trying add variable url. the page redirect not adding header variable redirect should.

try like

header('location: http://www.yoursite.com/new_page.php?gameid='.$gmid);

you need change quotes before variable or can try double quotes like

header("location: http://www.yoursite.com/new_page.php?gameid=$gmid");

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
