need a single, simple php page written. Connect to mysql database Prompt me for a date range create a table with the following: for specific date range grouped by username, date, then DataField. Need to count the number of times a specific exact url exists in a destination field, and divide that number by 3. So for a specific username, on a date, and for a specific datafield, there were 45 records that had a specific url in the contents of the field. So the answer displayed would be 15 (45/3). I understand mysql, and just learning php -- just need someone to wip up the page for me. I'll give you specific field names, etc upon awarding project. Not willing to pay more than $30... this is extremely simple.
