<dtml-if "which_table == 'Plays'"> SELECT * FROM <dtml-var which_table> WHERE "Play title" like <dtml-sqlvar "'%'+_.string.strip(form_string)+'%'" type=string>; Can anybody explain to me what is going on with my zsql method? Zope gives me the following error when I try and change my method to what is above. Invalid attribute name, "which_table", for tag <dtml-if "which_table == 'Plays'">, on line 16 of <string> I've scoured the mailing list, but I'm still mightily confused. which_table is one of the arguments for the the sql method and Plays is a string that I want to compare it with. which_table comes from a form elsewhere. I'm sure it's something really simple, and I'm sure it's been discussed here before (at length?), but ATM, I don't even know what I'm looking for! Thanks for the help tim
