[amruta_w]

Hello All,

I'm trying to send email using human task, in the human task for custom email template i have added the form variables but i'm getting following error 

ERROR freemarker.runtime - Error executing FreeMarker template

FreeMarker template error:

The following has evaluated to null or missing:

==> fullname [in template "custom-text" at line 1, column 9]

----

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</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
