FreeMarker template error!

FreeMarker template error:
The following has evaluated to null or missing:
==> dt_utilitycommunity.search[0]  [in template "ComponentTemplateSource:Utility Community Detail:8390" at line 7, column 22]

----
Tip: It's the final [] step that caused this error, not those before it.
----
Tip: If the failing expression is known to 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[/#if]. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
