Sure you're not looking for a type catalog?

Here's a much better one.  Just for fun, count how many time the guy says "confusing" or some variation of the word "confusing".

Please review my screen shot

The Lookup Value has to be in the First Column.

This table I created same way,

We have 

L, W, thickness. So we column is thickness,  look up value L 

Can you please check formula? 

size_lookup(table,"thickness", 100mm,L)

Honestly, I don't know how the heck this works or what you expect it to do, but your first mistake is the first value. Should be "look up table" not "table".

You should watch the video @barthbradley added, see if that helps you. Also you are using a type parameter, whereas look-up tables generally use an instance parameter. Don't know if it matters tbh, but that's from the knowledge page...

The size_lookup function is intended for instance parameters. If you want to use tabular data to define types with unique values for each type, create a type catalog
