I'm not great with excel (hence why I'm posting here), therefore I have little knowledge of the technical terms used to describe what I need to do.

Put simply, I sell signs. Customer orders a sign and specifies size (ie 1000mm x 500mm). The price is then affected by how many lines of text on sign. So two signs the same size, will cost different if they have different amounts of text. This is based on the number of text lines. So column 2 would have prices in for one line of text. Column 3 for two lines, and so on.

What I hope to achieve is a point where I can input the width and height of the signs, and the number of text lines, and have a cell which is autofilled with the corresponding cost.

Is this even possible?

Thanks
