My code is in the attachment alex.txt.
When i press the button for first time it gives me error: 'null' is null or not an object. But when i press it again or refresh the page and press the button it gives me the result that i expect.
When i change the var pdbfile1,2,3 values(for example with 2x4n;3gis;1crn) and press the button again there is the error again and i have to refresh the page again.
Can you please help me to to resolve this problem.

Jump to PostIE8 is more forgiving.
It retrieves and parses the XML file without error, then writes 275 (the value of 'ca1Length') as expected.

^The error 'null' is null or not an object may be the result of that or it may be something completely different; I can't tell without seeing more of the code.

Thank you so much for spending your time for me.
I'm using IE8 and it is still not working. Here is my all code. But please try puting different data for pdb1 and pdb 2 as
pdb1:3gys or "3D4X" or "3gis"
chain:a
pdb2:2x4n or "2QU0" or "1crn"
chain:a
and you will see that at first is not working and giving the error but when you click and unclick it will give the result.
just delete the row. You do not need that file. Sorry!
and this is the deleteme.php /which is not so important/
Provided that the values 2X4N:a 3GYS:a are entered before the checkbox is clicked, this version of test page
