'multiple visibility' Double lookup block - failure

[Anonymous]

I recently watched the following tutorial
Using Lookups to Imitate Multiple Visibilities 

I thought this approach might be useful for providing a materials selection, plot by plot, on a site plan.

After completing all the steps I tested my block out & got nothing.

I haven't seen any errors in my table entries. I am not sure if I should have labelled everything numerically (rather than alpha numerically) the tutorial above didn't caution you to do it a certain way, just to make sure it all matched across the various lookups.

Hoping someone with more understanding of lookups can give me a few pointers..

Your as-drawn parameters need to match a row on the tables they are used on.  Your 'Title no.' parameter is drawn with a distance of 5.01950302 and 5.01950302 is not found on any of the tables.  Similarly, 'Render' is drawn at 0.98311583 and 0.98311583 is not found on the tables.  

Don't use List values for your 'memory' parameters.  They do not help anything and only introduce errors.
