Use comma in numeric values

Hi

I am using the Dreamweaver MX insert behavior to insert records to a MS Access
database.
I have a web-form there my user will fill in some information for example
numeric values 4,5.
Is there a way for my user to write numeric values with comma (,) instead of
point (.) then insert records.

If i use comma (,) in numeric values i get the following error:

"Number of query values and destination fields are not the same"

In Europe we use comma (,) as decimal separator.

In other words i want to use comma instead of point.

Did anyone understand that

I am using the ASP insert behavior
