Square brackets problem

[hostagency]

Hi - I've a square brackets problem. I'm trying to run the following function in a php file to update the value of another field. Because source variable name is products_id[2] and the destination variable is id[2][10] it keeps failing. I've tried adding elements and various combos of quotes and brackets, but it just keeps failing. The function is:

function setAttribValue() {
var selectedItem = document.cart_multi.["products_id[2]"].selectedIndex;
var selectedItemValue2 = document.cart_multi.["products_id[2]"].options[selectedItem].value2;


if (selectedItem != 0) {
document.cart_multi.elements["id[2][10]"].value = selectedItemValue2;

}
else {
document.cart_multi.elements["id[2][10]"].value = "";

}
}

<select name=&quot;products_id[2]&quot; onChange=&quot;setAttribValue()&quot;>...etc etc

<input type=&quot;hidden&quot; name=&quot;id[2][10]&quot; value=&quot;&quot;>

Any advice?

Thanks

must you name your elements with square brackets?

Thanks for the fast reply.

I just realized I was missing the elements off the first var - got it working.

...document.cart_multi.[&quot;products_id[2]&quot;].selectedIndex;
...document.cart_multi.[&quot;products_id[2]&quot;].options

Should be-

...document.cart_multi[&quot;products_id[2]&quot;].selectedIndex;
...document.cart_multi[&quot;products_id[2]&quot;].options

No stop after _multi
