Hi, I have one quick question about the 'let' tag; <dtml-var expr="classcode_to_table(classcode)"> gives me the value 'class52225'. Is there anyway I can use the 'let' tag to push this onto the namespace stack? I was thinking something *like*; <dtml-let table expr="classcode_to_table(classcode)"> The python method, classcode_to_table, takes in a string, alters it and returns it. This is going to be an argument for some ZSQL methods and some Python methods. Thanks, Lee
