Please add the Row() Function. Not having that has been a huge headache for me over the last few weeks.
Reason: It would probably be easier than adding vlookup, and If I can reference the row number, I can tell something to always post at the top of the page which means I can have summary math on the same page as my information that is being updated. There are a lot of other features that could be added that would allow me to do the same thing, such as a special column that automatically has the correct row number in it (not auto-number, if a row is added at the top it inputs the highest number into that), I already mentioned V-Lookup/using math to reference other pages, giving the ability to have web pages update to the top of a selected row rather than row 1, giving the ability to only update part of rows with webforms and I'm sure that there are many other ways it can be done.
