It's related to your first issue. In your common.js, you have. Since 1 is greater than 0, calculate will be executed on each page load. Since that function consists of variables that look for elements with specific ids, such as t1. t1 does not exist on every page, so its innerHTML property doesn't exist. That code is probably meant for a specific page, but as it gets executed on each page, you get an error.
