[Zope] SQLForms and DEC()

[Stephan Goeldi]

I create a mysql table using SQLForms. Everything is fine, except one
problem: I'd like to create a field as decimal(7,2). But in SQLForms I
have only the choice of INT or FLOAT.

When I try FLOAT, the input of e.g. 375.5 or 375,5 gives me this error
message:

Error Type: TypeError
Error Value: not enough arguments; expected 3, got 2

The same I get if I create the table by hand using field type
decimal(7,2).

Does anybody know what the problem is?
