An error occurred while processing the template. 
The following has evaluated to null or missing:
==> formField.getValue().getString(locale)  [in template "20101#20128#SLIDER-HERO" at line 153, column 45]

----
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)??
