I want to output some data and using 'Output' and 'Lookup' functions.
If my DE fields looks like this:
Name Data Type. Length. Primary Key. Nullable. Default Value FIRST NAME Text 50 LAST NAME Text 50 EMAIL. EmailAddress. 254. x
What is the correct AmpScript to output someone's first name?
My AmpScript currently looks like this. I have a feeling my 4th argument is incorrect b/c I"m not sure what is the "Value that identifies the row to retrieve" according to docs.
%%[ var @firstName set @firstName = Lookup("DE__Test", "FIRST NAME", "EMAIL", EMAIL) Output(Concat("First Name: ", @firstName)) ]%%
