So in the example you gave, is math the name of a variable?

Yes and no. It is the name of the field (in zap, special fields are
called commands). When saved though, it also becomes the name of a
page text variable.

<pre wrap="">here is the syntax of my current zap form:
--------------------------------
(:input text E1 {$:E1} size=4:)
(:input text E2 {$:E2} size=4:)
(:input text E3 {$:E3} size=4:)
(:input text E4 {$:E4} size=4:)
(:input text E5 {$:E5} size=4:)
(:input text E6 {$:E6} size=4:)
(:input text E7 {$:E7} size=4:)
Total {(math
'{$:E1}+{$:E2}+{$:E3}+{$:E4}+{$:E5}+{$:E6}+{$:E7}')}
--------------------------------
what I want to do is assign the output of the math calculation to another
variable for use in another calculation.

Try something like this:
(:input text E1 {$:E1} size=4:)
(:input text E2 {$:E2} size=4:)
(:input text E3 {$:E3} size=4:)
(:input text E4 {$:E4} size=4:)
(:input text E5 {$:E5} size=4:)
(:input text E6 {$:E6} size=4:)
(:input text E7 {$:E7} size=4:)
(:zap math="{E1}+{E2}+{E3}+{E4}+{E5}+{E6}+{E7}":)
(:zap Esum="{math}":)
(:zap savedata="E1,E2,E3,E4,E5,E6,E7,Esum":)
Basically it calculates the sum then assigns that value to the field
Esum (you could just save it as math of course). So in the page
{$:Esum} should give you the total.
