A solution to your problem can be found at

As for data validations you might contact Les and ask for his advice. I believe your Visual FoxPro application will work with about one hour of required additional code to each of your existing form. Les gave a great session at the Silicon Valley Visual FoxPro User Group about three months ago on the topic of VFP Web Enabled Applications.
If you have to do data validation on a web page I would suggest VB Script or Java Script. Look into OnBlur() as it will allow code to fire if the user tabs through or drops a cursor into a data object. I do my data validations at the object level and also at the form.Submit() level. It might be overkill but my clients are happy and I can sleep at night.
