please help with combination of formulas, array, vlookup

Hi, altered and truncatedAttachment 357954


Need help finding a way to automatically rank from least to most expensive of the latest price only without deleting data. I will be inputing data all the time so it has to always change. Detailsdate is "timeline"), but compare the data with the criteria falls into the same category: type (usually electric or gas), utilities (many different ones), state, supplier (many different ones), usage bracket, and company.

Update: I tried assigning companies random ID #s using RANDBETWEEN, but I do not know how to have it automatically put them as an array. Please let me know if you have any possible solutions.
