}boxes. When a person chooses a value from the (key)
}selection box the other selection box will need to get
}its value from a database (postgresql) using that
}value as key. I'm using the onchange event in the
}form to call the javascript which in turn will open a
}new window ( another php script ) to access the
}database. My problem right now is I don't know how to
}pass the variables from the original php form to the
}javascript it is calling so that i can tell him which
}table to access, what variable to test those
}conditions, etc. I also don't know how to pass those
}information from the javascript to the new window (
}another php script ). And lastly how will the new
}window upon getting all the necessary data from the
}database pass it back to the original php form so that
}it can be seen in the selection boxes.

Sounds a little bit strange...

To give the data to any other window via javascript I define a js-function
in my form which opens the new window with the correct parameters.

OnChange will call this function with the parameters from your
form-input-field.

In the new window you can give back the values you need for your form with
the expression

opener.form.field.value=your_value_from_db
^^^^^^

But there are many examples in the web, which use this.
