Subject: Re: newby question on validation

You should be able to access this text field's value by referring to
@param. For example, here's a text input field that would appear in an
HTML form:

<INPUT TYPE="TEXT" SIZE="5" MAXLENGTH="5"
NAME="thisControl[thisNumber]">

You could access the value of this text field using the following in
your accompanying controller.rb file:

retrievedValue = @params['thisControl']['thisNumber']
render_text "The text field's value as entered is #{retrievedValue}..."

You could validate the value using conditional statements of the common
variety:

render_text "The value is too large" if retrievedValue.to_i > 100

Does this make sense?
