Can't submit an issue & formula field wrong type

Can't submit an issue & formula field wrong type

I've had a paid Zoho account for years.  I'm trying to log in to the support area, but I can't find a way to register.  Also, I called an left a message with your support.  I used to just send an email.  What's up?

Next, I have created a form with a formula field that is a product of a currency field and a numeric field.  The formula is defaulting to 'text' type (see attached), but should be currency or numeric type (since it is just 'Cost * Quantity).  How to fix?
