Why setting var in CFFUNCTION causes error

You say:
"I put these variables directly after my cfarguments."

But the error says:
"variable myVariable on line 60 must be grouped at the top of the function body!"

Please copy and paste the code, starting with <cffunction...> and down to <cfset var myVariable...>, exactly as it appears when you're getting this error.

Yes, this is the best practice to make the variable local to the
function. But you only need to use the var keyword once when you define
the variable. And you must define the local variables with the var
keyword at the very beginning of the function body. The only content
allowed before this happens are the argument definitions, i.e. the
<cfargument ...> tags.

If you have a variable that you don't need to use, you just need to
define it with a default and|or dummy value in the beginning of the
function. Then you can set it's value appropriately later in the
function when it is required. This is often done with query tag return
variables.

I.E.
<cffunction name="myQryFunction"...>
<cfargument name="someArgument"...>

<cfset var localQry = "">
...
<cfquery name="localQry"...>
SQL
</cfquery>

<cfreturn localQery>
</cffunction>

Because of this necessity to define all local variables at the beginning
of the function, a lot of developers use a standard where they define a
local structure. They can then just append new keys and values to this
local structure throughout the function. Personally I don't see much
advantage to doing this, but to each his|her own.

I.E.
<cffunction name="myQryFunction"...>
<cfargument name="someArgument"...>

<cfset var local = structNew()>
...
<cfset local.something = "FooBar">

<cfreturn local.something>
</cffunction>
