I'm trying to add a little Calculator function to a Spreadsheet I use for trading shares.
I pull basic data from YAHOO finance and would like to have at the bottom of a spreadsheet a calculator which would allow me to enter Nr of shares bought, Price Paid and return things like Profit / Loss.
The advantage of having it on the spreadsheet is then it's all in the same place.
The spreadsheet looks something like this -- enclosed pic
I'd like to embed the calculator in column M say starting at Row 15-- I'm not sure whether this should be done with a FORM or embed another spreadsheet.
Any ideas / links --- all the googling I've done either quote examples that are so impossibly complicated or hard or just too basic.
