using field values inside day-diff macro

[Dave]

This is a question specifically about Jed's day-diff macro: http://inmysocks.tiddlyspot.com/#Date%20Macro%20Demos

but it may have a more general application about using field values in macros generally

if I do this

<<day-diff 2019 10 14 2019 11 14>> days

I get this

31 days

but if I try these, none of them work:

<<day-diff {{mynow!!mynow}} 2019 11 14>> days

<<day-diff {mynow!!mynow} 2019 11 14>> days

where the tiddler "mynow" has a field called "mynow" that has value of "2019 10 14"

I also tried (didn't work):

\define mynowtext()
<$view title="mynow" field="mynow"/>
\end


<<day-diff <<mynowtext\>\> 2019 11 14>> days

thanks,

P.S. just realized 

<$view title="mynow" field="mynow"/>

should have been 

<$view tiddler="mynow" field="mynow"/>

but that didn't work either

Dave,

Also, If you want to pass transclusions, text references and variables into a macro like your first post, have a look at the $macrocall widget, because this allows you to have parmetername=value where value can be a variable or transclusion.

<$macrocall $name=macroname title={{mynow}} field=<<variable>> />

Post script;

If you need to concatenate something to get it into a parameter you usually cant do it inside the macro call widget's parameters, instead do this

\define variable(b) value$(variableA)$ $b$ and more

<$macrocall $name=macroname title={{mynow}} field=<<variable>> />

Regards

Tony

Thank you Tony, I'll try that out tomorrow.
