New Post: Need Help with spservices

I'm trying to use spservices to do this on a calendar form

list: a list of dates

i want the form to check against this list of dates if it falls within the range of dates picked on the date pickers. if it does i want it to count how many times and put that number in a column on the form.

I have bits and pieces but can't seem to put it together

If anyone has sample code to help me with would be great

thanks so much
