[munkynpunky]

Hey guys,

I'm trying to use one drop down menu - and select an item, once selected shows the cost up instantly in a form field nest to the drop down..

There are maximum of 5 items, each with 5 different prices.

Thanks for your help

This isn't php... it's javascript.
The trick here is making the php output the right javascript code. Depending on the complexity of your php, and how much of the html it generates, it could be easy or hard. Hopefully, it's not too hard.

Anyway, for the javascript code itself...

<select onChange="result.value=this.value">
<option value="1">One</option>
<option value="2">Two</option>
</select>
<input type="text" id="result">

Note: You might want to set an initial value in the textfield that matches the pre-selected option in the dropdown.

Hmmm ok, right, well its basically

year one = 3.25
year two = 6.50
year three = 9.75

and if i select year one i want to see 3.25 in a different readonly box next to the year selection...
