1, A greeting page asking for an obsolete part number.
2, When user enters the obsolete part number the webpage will then consult an excel file that has two columns "Old Part" and another column called New Part. (Mainly to make it easy for updating on a weekly basis).
3, Once the user clicks submit after entering the part number, the webpage will consult the excel spreadsheet and return the new part number so the user knows what the replacement part is.
Any help to do this would be appreciated, It should be quite simple but its knowing how to do it.
I dont have any knowledge of PHP and MySQL but would prefer it to be in this format if possible as that is what I have on my test web server at home.
