Field shows NAN

[shaikkhasim]

Hi Team

i have calculated the sum of subjects and i used to push out the total marks in the filed of total marks but in that filed instead of total marks it shows NAN error 

my script is as below 

if(newValue)
{
var t=parseInt(g_form.getValue('u_telugu'));
var h=parseInt(g_form.getValue('u_hindi'));
var e=parseInt(g_form.getValue('u_english'));
var m=parseInt(g_form.getValue('u_maths'));
var s=parseInt(g_form.getValue('u_social'));
var p=parseInt(g_form.getValue('u_physics'));
var sc=parseInt(g_form.getValue('u_science'));
var k=parseInt(t+h+e+m+s+p+sc);
g_form.setValue('u_total_marks',k);
}
}
