accepting form data and store it in mysql and display the contents in a html form

hi! my name is ramesh and i am looking after a web page in an office where in intranet connected 21 sub offices. My problem is these 21 branches have to give some business figures everyday evening. I have to display them in a html form to the managers in the controlling office as well as to the suboffices to see the others business figures. My web page in windows-sambar server-php-mysql enabled. I am not proficient in PHP but I can modify the scripts that are freely available in the net. How can i convert the data keyed in forms to tables in mysql and display them in html form. I also want to display only todays figures. if any suboffice doesn't keyin the todays figures the html form should not show any figures. Can anybody suggest or write any php script?
