Default Excel Help - Market Framing

Hi Guys,
I got a problem with re-adjusting markets to take scratchings into account.

It seemed so easy, but when I sat down to do it I realised I had not clue one what I was doing. I went to an Excel help site, but realised it would be easier to explain to the racing mob.

What I want to do is write a template for up to 20 horses (the max I expect to encounter), so Column A = TAB No, Col B = Original Market, Col C = Adjusted Market after Scratchings.

My first problem was establishing the market percentage of Col A.
It went something like - =SUM(100/B1+100/B2+100/B3+100/B4+.....100/B20) which apart from being incredibly cumbersome doesn't take blank cells into account and there returns a #Div/0! error. So I started playing around with conditional functions and, and..... I've got a headache....

Surely one of you very charitable souls can point me in the right direction, I'd REALLY appreciate it.

Thanks,
Den

I've quickly put together...

Market Maker Deluxe

Simply delete the rating of any scratching and the market will recalculate to 100%

Hope this helps.

Thanks Chrome, certainly a professional looking job but you misconstrued what I meant, or more likely I didn't explain very well.

What I wanted was to put in a column for paper prices and have it auto recalculate the odds after scratchings.

I finally got it done - very messy, took 6 columns although 3 of them can be 'hidden'. I knew there was a way cause I can sit down with a calculator and pencil and achieve the result. There may be a more efficient way but it works.

I have attached the file in case anyone else wants it.

Market Adjuster Gold

Note: In this example 3 & 10 are scratched.
