I am messing with TinyTablePlus which has NULL as the value for one of the ID column. How do I test for NULL? <dtml-in expr="testtable.getRows()"> I have tried... <dtml-if "ID==''"> <dtml-if "ID=='Null'"> <dtml-if "ID==Null"> <dtml-if "ID==None"> I don't know if NULL is a string, a non-entity or what? Thanks, Trevor
