Keep in mind that the syntax you're using for setting dynamic variables is
unsupported; you should probably use the SetVariable function instead - it's
a lot less likely to accidentally disappear in future versions of CF.
Besides that, though, there's a bigger problem, which would prevent you from
using SetVariable in this case as well. That problem is that a member of an
array isn't exactly the same as a "variable" from CF's perspective. The
array itself is a variable, but if for example you attempt to check for an
array member's existence using IsDefined, you'll get an error there as well.
Instead, you could do something like this:
<cfset rs = Evaluate("ArrayAppend(TempArray[1].GroupAccess, 'hi')")>
