PHP script to save partially completed on-line work

Estimated duration: ASAP
Description: We have a crossword compiler that generates crosswords, used to teach vocabulary to both local and foreign children living here. The crosswords are available on line. The crossword compiler allows for the users to save partially completed crosswords, and return to them at a later stage. It comes with a non-functioning CGI script which is supposed to allow users to save. We are looking for a php programmer who can work with us and develop a working script that will allow the children to save their work. If you are interested, contact me and I will supply URL's etc to sample crosswords.
