How do I make a list in Mathcad Prime

Hello, I am trying to do a "list" of numbers in Mathcad, like that :(4.6, 5.6, 8.8). It is for programming purpose as I want to do an "If" condition if my variable is equal to one of those values. What I really want to do is get α_v in function of the grade of the bolt and if the shear stress passes through the threaded portion of the bolt (see pic).

You need to create a table and use the "match" function.  Attached is Prime 4

    As so often there a many ways to achieve the desired goal.

    You may add the variable value for alpha as an output of the first combobox and override it by the single value 0.6 in case that the second combobox returns "no".

    In a combobox it is not necessary to provide the first column of display names. If you don't, the first column of return values is used instead for display. There is also an option to hide the left hand side with the variable(s) of a combobox and you can assign the output of a combobox to a vector of variables.

    I made use of this and you can see how if you select a combobox (right mouse click) and chose "edit".

    Unfortunately what PTC implemented as combobox is very basic and limited. Otherwise it would be able to use variables in the return vectors and so selecting "yes" could return alpha_v and "no" would return 0.6. That way we could do without the region with the if function. Maybe PTC will improve their unfortunate creation in a future version.
