Alias() is not a safe thing, it will bang in the end if you had nothing in the current workarea. Also, you don't even have to keep the record number... just open your cursor again:
Lparameters tiQuoteNo

lnSelect=Select()

Select 0
use dbf("Quote") again alias (sys(2015))
Sum (qty*price);
 For quote_no=tiQuoteNo And Print=.T.;
 To Thisform.nQuoteTotalPrice
use

Select (lnSelect)

Return Thisform.nQuoteTotalPrice
