Hi All,

I've been tweaking this for a few days. & i can't seem to get it working correctly in IE, however it works well in Opera & Mozilla + Netscape. O guru, help me see the light. Javascript isn't as straightfwd as other OOPL's

the outline is this

|Make |--- |Model|---| Year |

-- Change of make rewrites models.
Change of Models re writes Years.

-- Makes are hard coded.

-- Make/Model/Years is in a 3 dimensional array. Each entry unique to make / model combo. the year component is a ":" separated list of all years relevant to that make--model combo.

If the code below is illegible pls see attachment.

----code below----
