I have a global variable called `@Count`

. I also have a for loop that increases the `@Count`

by 1 each time I cycle through the loop. Is there a way for me to detect with AMPScript whether `@Count`

is an odd or even number?

%%[ /* SET GLOBAL COUNT VARIABLE */ SET @Count = 0 /* INCREASE THE COUNT BY 1 EACH TIME */ FOR @i = 1 TO @increaseCount DO SET @Count = Add(@Count,1) NEXT @i /* DO SOMETHING IF COUNT IS EVEN OR ODD NUMBER */ IF @Count == "even" THEN BLANK ELSEIF @Count == "odd" THEN BLANK ENDIF ]%%

### Method 1

I’d suggest using the **MOD()** AMPScript function. If `@sum`

is evenly divisible by 2 then it’s even, otherwise it’s odd:

%%[ var @i, @sum, @max set @sum = 0 set @max = 10 FOR @i = 1 TO @max DO SET @sum = Add(@sum,1) NEXT @i IF mod(@sum,2) == 0 THEN output(concat("<br>", @sum, " is even")) ELSE output(concat("<br>", @sum, " is odd")) ENDIF ]%%

### Method 2

Try using `MOD(@Count, 2) == 1`

. Here is the documentation for the `MOD`

function. If it’s 0, you’re even. If it’s 1, you’re odd.
