Joe,
You wrote:
//calculated total
forvalues i=4(11)386{
local j='i'+4
replace total=total+var'i'*var'j'
}
Then Stata 8.2 informs me
'i' invalid name
r(198)
Your problem is the single quotes. The left single quote is ` (grave).
It may be on the upper left corner of your keyboard, or it may be
elsewhere. It may also be a dead key, displaying nothing until you hit
the spacebar.
The Stata manuals are not very explicit on this, and you are not the
first who had this difficulty.
