What was the problem reported? The second loop should start 

foreach y of local quantity {

I am working with a dataset that has quantity variables named like -capital- and -labor-, and price variables named -pcapital- and -plabor-. I am trying to use -foreach- loops to create expenditures and their sums but my syntax is wrong. I'd appreciate suggestions to fix my syntax. The example follows:

local inputs "livestock material labor capital land"
foreach input of local inputs {
	replace `input' = -`input'
}

local quantity "grain sheep other `inputs' "

gen profit = 0
foreach y of quantity {
	gen exp`y' = `y'* p`y'
	replace profit = profit + exp`y'
}
