Another Web Project

My latest web project allows people to purchase photography online. The hosting company allows shopping online but only if you use their Site Builder software to build the page. The software is not bad but I couldn't do much behind the scenes to give it much razzle-dazzle; every time I attempted to adjust the codework to improve something the forms would stop working. The good thing is that the people I did the site for can update it themselves. Less maintenance for me and more control for them. Let me know what you think. And let me know if any of you know a work-around for the forms breaking when the code is modified.
