Trigger a Form from another Form (Inline Frame)

Trigger a Form from another Form (Inline Frame)

I have two key Forms (A) Which is a set of dates with associated prices and (B) A simple form to request a quotation

Both forms are displayed on a web page as iframes (one above the other).

Ideally I want to be able to select a date form the calendar form, then pre-populate the quote form with the specific data from the calendar form (eg - date, price & location).

Whilst I could build a field in the calendar form as a URL to call the Quote form with pre-populated fields, I dont see how I could do it to then display this pre-populated form in the associate Iframe ?

Any suggestions

Thanks

Neil
