[amibroker] Using writeif in Addtextcolumn

["stephen_castleden" <stephen_castleden@xxxxxxxxx>]

Hello,
I would like to use writeif in this way in an exploration:

AddTextColumn(WriteIf(alphafast,"Alphafast",WriteIf
(alphapf,"Alphapf","Alphanp")),"Signal Type");

but this only ever writes the last string (even if first condition is 
true). Could someone let me know how I can write this code.

Thankyou,
Stephen :-)
