SMFC TIP | NULL value comparison in IF statement

If you have field in DE that its value is not always populated for a particular row (customer) and you test field value against any value cloud page will throw an 500 – internal server error.

To fix this you will need to add another AND-condition to test field value for NULL

%%[
var @field;// null value


if @field == 4 then
//500 
endif

]%%
