multi text input for search with a date, source, and location dropdowns

I am currently working on a dashboard that will simplify the search for some of our office personnel who are not Splunk savvy. I am creating a dashboard that has three drop down and six text inputs in order to ensure they are getting the specific results they are looking for, however I am not sure if the code is working and why the submit button are not working. I am very new to XML and any help would be appreciated. my code: Splunk made simple Date and Time@dnowSelect SourcechoclatesveggiescakespiesFoodAllFoodfood_nameindex=goodies source=$source_token$ | stats count by food_name@dnowWho$user_tok$Trainer$uid_tok$First meal$src_tok$Second Meal$dst_tok$third meal$junkfood_tok$Snack$snack_tok$index=goodies source=$token_time$ | fillnull value=NULL food_name, user, uid, src, dst, junkfood, snack | table food_name, user, uid, src, dst, junkfood, snack |$time_token.earliest$$time_token.latest$10nonenonetrue
