[pmwiki-users] zap - save math output to a variable

[Karl]

I am using a form to save numeric values to a series of variables.  Then 
I use math to output totals of of those variables to the pmwiki screen.  
What I want to do is assign these totals to other variables so I can 
perform further calculations on these totals.

Can anyone help with the syntax needed to do something like this.
