The block started by "if(...){" isn't complete - it needs a matching "}"
before it is.  As such, the "else" is just hanging by itself.  An "else"
with no corresponding "if" is a syntax error.  This would be correct
(UNTESTED)

if (exists("f")){
  dt <- read.csv(file.path(d,f),header=F)#data frame
  builddl(dt,f)
}
else
