create formulas and functions on excel

Hi Guys,

I'm looking for some assistantance with excel. I have been attempting to set up the following but have had no luck:

Basically,

'in the first box I would to type a start date

'Second box should find or show the available info for that date range (the range of dates and info will be available to use for fomulas)

'Third box should then generate a 'a link or file path for the correct set range of data I have listed'

Now, I need some assistance as to how to set this up on excel, any ideas?

Thank you.
