Short deadline 1 page php/javascript web page

Hey i really need this done by monday morning sorry for it being really short time period. I already have most of the page done but it doesnt look very good and there are a few issues as stated below. the page allows users a person on a mobile or dekstop to enter one row and then there be a plus button to add an extra row where they can add more results

• Sort out all of the css so that all of the data entry tables are the same size and in line
• Make it so that when you click the first remove button it actually removes the row rather than sending to an incorrect page which it does
• When you start typing it looks through the first names + second names in an existing table and then gives an automatic suggestion of whom you are typing and then you can click on it and it will load their first and second name in the box and it will load the rest of the variables so that it can be put into another table called “full_results”
• Create a drop down menu where you can select the different sports and then it will apply that event to all of the data entries under the column “EVENT”
• When you press submit all of the results are sent to the database full results it doesn’t need to check for prevous entries as it may need to have multiple entries from the same pupil
• Prevent the data entry from submitting if the name is not selected from the data base and tell them which row has the issue
• Prevent the data entry from submitting if the result is below 1 and above 100 and tell them which row has the issue
• Make all of the page viewable on both a mobile and desktop (responsive)
• It must run reasonably quickly even on an iphone 4 and ipad
• Not use too much of the databases rescources as 30 people might be doing this all at the same time plus 200 others all trying to read data from the results table
• Prevent sql injection
