I am attempting to create a form that will have several checkboxes, but I want people to be able to only select two. Or, if I can use radio buttons that would be fine also, as long as two can be selected at once in the same group. How do I do this?
John Brinkmann has written 3 spearate blogs on exclusion groups and shows how to do this. Here is the 3rd entry, it has links the the other two inside.

The following has evaluated to null or missing:
==> liqladmin("SELECT id, value FROM metrics WHERE id = 'net_accepted_solutions' and user.id = '${acceptedAnswer.author.id}'").data.items [in template "analytics-container" at line 83, column 41]

Tip: It's the step after the last dot that caused this error, not those before it.

Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
