Could you please give us an example of the misbehaviour?

when max marks is 1000 and entered obtained marks is more than 1000 it's doesn't work...

how do you treat numbers greater than 1000 in your app? I mean depending on the culture it might be 1 000 or 1,000. And whereas parseInt("1000") is actually 1000, parseInt("1 000") or parseInt("1,000") is actually 1.

What are the actual values in the case where you think it does not work?

I just tested your code and it works fine. You must be doing something else wrong. As I said before, what are the actual values of the two variables in the compare expression?

I have checked your code,
can you check with alert above if condition :

"alert("txtGMarksObtain" + txtGMarksObtain + " and " + "txtGMaxMarks" + txtGMaxMarks);"

you got the value or not, i think code is working fine but just check in console you got the any error.
