Automatically selection Table value

Dear all,

I would to create a calculation sheet in Mathcad 15 where when I select an option the reference value are automatically selected.

For example:

In the previous table I would select the value determined by weld condition (full penetration) and quality level 2.

I would to create  a windows that, when I select this two condition, the referring value is automatically selected.

Best regards

Stefano
