result is NaN
Well, Ahmed, the values you are attempting to set for items1, item2 are not initially set on documentLoad.
Give them an initial value in the HTML and you won't get the NaN:
If you are supposed to be waiting to calculate the value, you should set item1-item4 in the .change. Can you try to explain a little better what you are trying to do here?

and you should put the calculation of your variables into the change event, else they will always stay static!
to handle NaN error, you could use isNaN in your codes:

The same way you initially did it:
var item1=parseInt($("#markup").val()) / x ;
var item2=parseInt($("#mark").val());ASKER
