Preparing final area crop dataset for Validation

dat.SPAM.EU = dat_spam_global %>% #Pixel level data
  filter(iso3 %in% EU_iso3) %>% 
  group_by(iso3, crop) %>% 
  summarise(sum(H), sum(A)) %>% 
  left_join(., dat_country, by = "iso3") %>% 
  dplyr::select(iso3, crop, `sum(H)`, `sum(A)`) %>%
  rename(HarvestedArea_ha = `sum(H)`,
         PhysicalArea_ha = `sum(A)`) #%>% 
  left_join(., dat_country, by = "crop") #%>%
  dplyr::select(iso3, Country, crop_SPAM, `sum(H)`, `sum(A)`, crop_SPAM_long, FAO_no, crop_FAO) %>%

Thhis code is not fully working. I want to sum H and A by croop and country. Doesn't work. Must be a typosomewhgere...
