problem:

the html table isn't loading upon pressing button.the php page working when change form's action "delsubcategory.php" , button type="submit", issue lies html.

would appreciate insights matter

you forget wrap button click event handler $(function(){ });

<script type="text/javascript"> $(function(){ $("#viewsubcatsubmit").click(function(){     var cat=$('#viewsubcat').val();     $('#deletetable').load('delsubcategory.php?cat='+cat); }); }); </script>

(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...
