This is f***in awesome! I found my old cards in the basement a few weeks back and now I’m reliving my teenage years from Unlimited all the way to Urza’s. Thanks so much for putting this up, it really helps with how I’m going to be buying and selling cards to create a great collection.

Thanks again.

Thought I’d follow up, turns out the error occurs when cards in the reference list aren’t sorted in expected ascending order, changing the formula to sort?0 finds the missing itmes and correctly displays. I’ve continued past your tutorial to set up some additional funcitons, having fun with it, let me know if you’re interested in hearing the details.

Thanks for the tutorial, Jason!
Getting a baffling error I wonder if you’ve any guesses how to solve. Using the function as you have written for column 3(c), and the validation setting for 1(a), certain cards return a false price value of 0.25. Changing the card name to a different name returns a correct value, so the validation and formula appear to be correct. Changing quantity correctly multiplies the value to Q*.25. Typing a nonexistent card name (ie “faketest”) returns the same .25 result. Now why, even using the dropdown menu to directly select a cardname (in this case, using the latest pricelist, the error card is Dromar the Banisher) would the function be unable to find and match the cardname? When I encountered this error I went into problem solving mode and I’ve now skipped 4 hours sleep to no gain. Baffled and intrigued, look forward to any light you can shed.

Good point matt!

I guess the next step would be to find a site that has a better range of prices & try and scrape those values together into a database.

My friend Brian also asked if we could figure out a way to keep historical data on each card. I’m sure it’s all possible! When I have time I’m going to look into web-scraping based off a pre-defined list of cards (i.e. the ones we now have). I’m hoping that I can write a visual basic script that will run through the list, scrape a web page for the right info & add it to the spreadsheet, giving us historical data, prices based on card condition, and a glimpse of how rare or common a card is.

In fact, it might be better to just write something like this in PHP and make it a web page..

hmm..

Wow!….

And what about card condition? I mean, a poor or a played Ancestral recall does not match the price of a mint one…

Let me know if you get $3,000 for one of your cards.

Heck let me know if you get $500 for one of your cards.
