Try this...

let startDate := date(2016, 8, 1);
let endDate := date(2017, 7, 31);
if dateField >= startDate and dateField <= endDate then
text("16 / 17")
else
text("Other")
end

Check out “Switch Case” in the language reference 

I just suggested it because it is well suited for what you are doing here.

My bad! I was distracted when I posted that. Switch evaluates a single expression which you then check for possible results. You are testing multiple expressions. I am very sorry for the confusion!

Hi slowwagon,

hi Andrew,

this can also be realized with switch:

---

let YS14 := date(2014, 8, 1);
let YE15 := date(2015, 7, 31);
let YS15 := date(2015, 8, 1);
let YE16 := date(2016, 7, 31);
let YS16 := date(2016, 8, 1);
let YE17 := date(2017, 7, 31);
let YS17 := date(2017, 8, 1);
let YE18 := date(2018, 7, 31);
let YS18 := date(2018, 8, 1);
let YE19 := date(2019, 7, 31);
let YS19 := date(2019, 8, 1);
let YE20 := date(2020, 7, 31);
let YS20 := date(2020, 8, 1);
let YE21 := date(2021, 7, 31);
switch 'Learning start date' >= 0 and 'Learning start date' <= date(2050, 7, 31) do
case 'Learning start date' >= YS14 and 'Learning start date' <= YE15:
"14 / 15"
case 'Learning start date' >= YS15 and 'Learning start date' <= YE16:
"15 / 16"
case 'Learning start date' >= YS16 and 'Learning start date' <= YE17:
"16 / 17"
case 'Learning start date' >= YS17 and 'Learning start date' <= YE18:
"17 / 18"
case 'Learning start date' >= YS18 and 'Learning start date' <= YE19:
"18 / 19"
case 'Learning start date' >= YS19 and 'Learning start date' <= YE20:
"19 / 20"
case 'Learning start date' >= YS20 and 'Learning start date' <= YE21:
"20 / 21"
default:
"New Year Required"
end

---

But you can also do a lot easier:

---

let myDeadline := date(year('Learning start date'), 8, 1);
let myYear := number(format(myDeadline, "YY"));
if 'Learning start date' >= myDeadline then
myYear + " / " + (myYear + 1)
else
myYear - 1 + " / " + myYear
end

---

so you can calculate all years without limit

Thank you Leo!
