FileMaker Server with web browser interface for intranet

[Osman]

Hi,

I want to use some of clients in intranet web browser to see datas (not for data entry) in order to reduce cost. ( at most 30 clients use browser)

Data entries will be entered from filemaker clients.

For this solution i should purchase filemaker server or filemaker server advanced ( i dont need to publish on internet just intranet) or can i reach data in FMServer via ASP?
