hi serenity.

Rule 1) You must solve it by using Regex.

IF statement is allowed but you've solved it through IF Between rather than Regex.
year of birth Validation also need to be proceed through RegEx.

Can I ask why you put unnecessary quote tags around your message like Skan often does? On my screen it makes text hard to read, so I only went by the code examples as a guideline.

i was trying to have better readability by splitting questions into quote boxes. didn't realized that it could be looked like that. i'll reformat it. neways your 2nd regex doesn't match to expected output

#1:

Total of 17.

#2:

Total of 30.

I get the correct output. google.com/ncr redirects me to .co.uk so I probably don't have the same source as you.

@ Titan
i know that you're the person who can obtain all the hall of fame for regex stuff
but i was talking about the url header whether http://www.google.com or http://www.google.co.uk

The image URI is relative, so to put a new string before it has nothing to do with regex. You could easily pull "www.google.co.uk" from another part in the HTML source but there is no guarantee it is the same host of the resource in question i.e. my copy could be from a proxy or downloaded directly from IP.

This returns blank for me. I wonder if it's a locale thing.

For some reason AHK won't let me use (110 src="(.+?)") or (110 src="([\w\D]+?)") in a script. I've run into this before when trying to match " character in regex.

You need to put two quotes in a row to escape them inside a quoted string.
