Dave,
First thing I notice is
val="{{||vasSumGraph}}"
The contents will be passed as a literal string. Use this instead.
val={{||vasSumGraph}}
When using macros or transclusions the delimiters they use such as `<<` and
`{{` doubles as a way to delimit themselves.
Additional delimiters just say you are passing a literal.
If in doubt calling any macro including your own, use the macrocall widget
<$macrocall $name=sparkl varname={{||vasSumGraph}}/>
I do not see the macro sparkl defined so I guessed varname
Note the use of $name this keeps the possibility of using a "name"
parameter in the macrocall.
Macrocall lets you pass parameters from various macros and transclusions
including fields, tiddlers text references even from something constructed
with triple curly braces.
{{{[all[current]addprefix[$:/namespace/]]}}
The short form of macrocall is basically limited to the following
<<macroname "firstparamvalue" namedparam:"Value for named param">>
Although inside a macro you can use $(varname)$ and $parmname$
So one macro calling another can say
<<macroname "$firstparam$" namedparam:"$namedparam$" 3rd-param:
"$(currentTiddler)$">>
I hope this quick briefing helps. It is all documented but takes time to
bring this together in ones head.
Regards
TW Tones
