Selection of Data in tables

Hello all,

I am planning on making my Mathcad sheets more efficient and wanted the sheets to select by themselves from tables the properties of steel sections as shown in my screenshot. And recieve an output in my calculation sheet.

Unfortunately I have not come to a good solution. I managed to reference for example three different sheets with for 3 section types (each sheet has one table with all the section properties), but once Mathcad discovers the desired section in a row ( lets say row "x") it also goes into the following referenced sheets and reads the line x in all tables and gives me the output from the last sheet I referenced.

How can I make Mathcad stop reading tables once it found the right table? Or do I have a completely wrong approach to it?

Thank you very much already for your help,

Joe
