Custom Web Form Help

We need someone to evaluate a current custom web form script we have now. The programmer needs to make sure everything is correct with the script. We also need a progress bar for uploads and an error log system so we can see when people have errors with the uploading. The way the custom web form works right now is that someone within our organization uploads a file through a staff panel on one server. Then, a custom bash script takes that uploaded file and sends it to another server at the top of each hour. Then, the file is ultimately displayed on a website hosted on the server the file was transferred to. We just need someone to go over the coding and make sure it works, with the addition of the error log system and progress bar. Also, testing for all browsers will be needed.
