Finance Year to Date Balance

Using the Value Entry table, does anyone know the best way for me to calculate a finance year balance based on TODAY’s current date without user input?

Do you mean inventory valuation? And what do you mean by “Without User Input” [?] NASA have developed a new type of vocal cord analyzing tool, that can read nerve movements before the user actually speaks, and interpret these as suggestions from the brain. Basicaly there is no physical movement by the user, and no speach, so technically that would classify as "No User Input right [:D][:(!][:D]
