I am outputting data in a data report that needs to be placed in the page header and need to output information in the report footer that does math on another field in the footer.

The header needs to have data that shows the version of the report being printed, but may be revisable by the administrator of the software. I did this by placing the information in an Access table (all data is in Access) that only the administrator can modify.
However, I can not place a text box in the header to get the data from a SQL query that the report is linked to. Is there any workaround for this issue.

Also in the footer I need to show 10%, 20% 80% and 100% of the sum of one of the columns in the report. I can get the 100% using the sum report function, but no way to reference that multiplied by the appropriate fraction.

This is for a project I need to finish this week and I can find no way to achieve what I need. Any help would be greatly appreciated!!
