HTML Code:
dim a , b,c
a=40,b=30
c=a+b
result=4030
while desire result should be 70
thats weird....manojkumarmaithil

... because The Host should interpret your variables to be variant... it means that base from your code the result should be 70...

But it seems to me that theres just something wrong in your code...

please refer to line number 2 of your code... You cant do a comma when assigning values... try this one instead...
------------------
dim a , b,c
a=40
b=30
c=a+b
msgbox c, "Result is"
