Here's the basic concept:Start with template #1 - the 'append' template. This is where you let your users vote. When they make their choices and click the 'Submit' button, this form appends the data to the 'votes.db'. For simplicity, let's say you give your voters a simple ballot with only two possible responses: Yes or No.When the user makes his/her choice and clicks the Submit button, WebCatalog 2.0 appends a new record to the votes.db database file which includes the 'choice made by that voter - either 'Yes' or 'No'. Now here's the fun part ...In template #2 - the 'results' template - you put two different [search] contexts. Make the first [search] retrieve all the records with a 'yes' vote in the 'votes.db', and put a [numfound] inside this search context like this: Number of 'Yes' votes = [numfound]Now, do the same thing with the other [search] context, but make this one retrieve all the records with a 'No' vote, and label this one: Number of 'No' votes = [numfound]. That's all there is to it!This example is very basic, of course, because it shows how to do it with just two choices. But you can expand this technique simply by adding another [search] context for every new choice you give your voters.If you have five different choices on your 'append' template, you put five different searches on your 'results' template ... :)Sincerely, Ken
