By adding # to a parameter, Quaestor automatically assigns it the TeLiTab dimension. Similarly, a $ assigns a string dimension (see also QuaestorSyntax). The relation defines that GM, GM_rounded and Ship_no should added as goals in the Ships object for each case (B and Lpp combination). Stability# will contain the data from the original selected object Ships, augmented with the three columns and all data needed to calculate these results.
Make sure Stability# is determined by system/function.
When solving for Stability#, is needs the object Ships. If you select the object Data in the Dataset, the object Ships is available, because it is an object within Data.
