Thanks for everyone that's helped me out with my Wash questions. I have one more.
I have a textInputField that I only want to display on a form in certain cituations. I can't figure out how to make this work. For instance:
... do if cond then x <- textInputField ... else () ... submit ...
Well, two problems there... first, the scope of the x doesn't reach to the submit. Second, there's a type issue. So I thought maybe I could figure out something like this:
Well, how could this possibly work (that is, how could 'x' be visible at the point of submission)? If you go down the 'else' branch, what value should x have? The scoping rule is like that for a very good reason... Once you know what value x is supposed to have down the else branch then you will be able to do something like: x <- if cond then textInputField ... else return ... Jules
