User Iput via Dropdown Box and then Separate Cell Calculates based on Options Chosen

Hi and welcome to the forum )

I would suggest that you combine all the answers from the D/D in 1 cell (you can hide that if you want. And then use a helper column newxt to the table with all teh data in it, and do the same thing there for each cell. then you can do index/match against the helper

Can you post a SMALL sample file so we can see how your price table is setup?

It's not exactly what I would call "intuitive". Here's what it says in the forum FAQ:

How do I attach a file to a post?

To attach a file to your post, you need to be using the main 'New Post' or 'New Thread' page and not 'Quick Reply'. To use the main 'New Post' page, click the 'Post Reply' button in the relevant thread.

On this page, below the message box, you will find a button labelled 'Manage Attachments'. Clicking this button will open a new window for uploading attachments. You can upload an attachment either from your computer or from another URL by using the appropriate box on this page. Alternatively you can click the Attachment Icon to open this page.

To upload a file from your computer, click the 'Browse' button and locate the file. To upload a file from another URL, enter the full URL for the file in the second box on this page. Once you have completed one of the boxes, click 'Upload'.

Once the upload is completed the file name will appear below the input boxes in this window. You can then close the window to return to the new post screen.

What files types can I use? How large can attachments be?

In the attachment window you will find a list of the allowed file types and their maximum sizes. Files that are larger than these sizes will be rejected. There may also be an overall quota limit to the number of attachments you can post to the board.

Try this...

Fill in the color cells so that every cell contains a color:

B3:B6 = Red
B7:B8 = Blue
B9:B11 = Black
B12:B14 = White

Then, enter this array formula** in K13:

=MAX(0,IFERROR(INDEX(D3:G14,MATCH(K3,IF(C3:C14=K4,B3:B14),0),MATCH(K5,D2:G2,0)),0)-N(K10))

** array formulas need to be entered using the key
combination of CTRL,SHIFT,ENTER (not just ENTER).
Hold down both the CTRL key and the SHIFT key
then hit ENTER.

Where some combinations are not available the formula will return 0. For example, there is no blue Lexus so the result will be 0.
