Disable 2 checkboxes based on another checkbox

Hi,

I've been searching high and low for a 'simple' script to help me do the following:

1. Have 2 checkboxes (out of a group containing 3) disabled when the form is opened.

2. When another checkbox is ticked (one in a completely different group, containing a total of 8 checkboxes), the original 2 disabled checkboxes are activated.

I've tried many forums for hints and tips but I can't seem to get any of them to work. My problem may well lie in the fact I'm sending the form data to another .asp page.

Any help would be greatly appreciated.

Use the onclick event on the tickbox object that will activate the other to. Write a function that sets the two checkboxs to disabled = false. This is easily done if you give the checkboxs ID's. How far have you gotten?
