repopulating drop down menus

[rogerhadden]

Using the script below, I am trying to repopulate some drop down menus - depending on a previous choice. - the repopulate bit works, but I am unable to select any of the items from the new menus???

function upDate(){
if(document.choices.Form.value=="LM granules, Practitioners Only"){
document.choices.Size.length=0
document.choices.Size.options[0]=new Option("2g LM-Granules £4.75","2g LM-Granules £4.75")
}

if(document.choices.Form.value=="LM liquid"){
document.choices.Size.length=0
document.choices.Size.options[0]=new Option("15mlm - teat dropper (10% alc)(£4.20)","15mlm - teat dropper (10% alc)(£4.20)")
document.choices.Size.options[1]=new Option("30mlm - teat dropper (10% alc)(£4.40)" ,"30mlm - teat dropper (10% alc)(£4.40)")
document.choices.Size.options[2]=new Option("50mlm - teat dropper (10% alc)(£4.50)","50mlm - teat dropper (10% alc)(£4.50)")
document.choices.Size.options[3]=new Option("100mlm - teat dropper (10% alc)(£4.75)","100mlm - teat dropper (10% alc)(£4.75)")
document.choices.Size.options[4]=new Option("150mlm - teat dropper (10% alc)(£5.00)","150mlm - teat dropper (10% alc)(£5.00)")


}
if(document.choices.Form.value=="Tablets"||document.choices.Form.value=="Pills"){

When you say you are "unable to select any of the items", do you mean that:

- The list box is unclickable?
- The list box is clickable but the options are not?
- The list box and options are clickable, but the list box does not change to your clicked option?
- The list box and options are clickable, but the form does not post the chosen value?
- Something else?

Also, have you tried multiple browsers? If so, does the problem happen in all of them?

Either way, check out faq216-6294 for more on dynamic listboxes.

Hope this helps,

Thanks Dan

The problem i find is that the second drop down will re-populate with the code, the options will highlight, but the option selected does not appear in the box.

Your link looks good - will try and adapt that to my needs.
