Math help with shortcodes

HI
New to this and switching from custom content shortcode.

I have been using these in ccs:
[set v1][calc][gamipress_points type=“trees” columns=“0” thumbnail=“no” label=“no” current_user=“yes” inline=“yes” wpms=“no”]+[gamipress_points type=“acorn” columns=“0” thumbnail=“no” label=“no” current_user=“yes” inline=“yes” wpms=“no”][/calc][/set][format thousands=,][get v1][/format]

[format decimals=2 point=. thousands=,][calc][get v1] * 0.025[/calc][/format]

I am trying hard to replicate this in L&L. I have tried this:

<Math><Shortcode gamipress_points type="trees" columns="0" thumbnail="no" label="no" current_user="yes" inline="yes" wpms="no" /> + <Shortcode gamipress_points type="acorn" columns="0" thumbnail="no" label="no" current_user="yes" inline="yes" wpms="no" /></Math>

and

<Set name=tree_total>
  <Shortcode>[gamipress_points type="trees" columns="0" thumbnail="no" label="no" current_user="yes" inline="yes" wpms="no"]</Shortcode>
</Set>
<Set name=givetree_total>
  <Shortcode>[gamipress_points type="acorn" columns="0" thumbnail="no" label="no" current_user="yes" inline="yes" wpms="no"]</Shortcode>
</Set>
<Math><Get name=tree_total /> + <Get name=givetree_total /></Math>

Individual values will work. But I cannot get the Math function to add them to together.

Any ideas would be great… thanks
