I forgot that it should be quotes around the name, i.e:


document.all["LAB<%=live%>"].disabled = false;

yes it would, providing that the ASP variable live contained the appropriate
value.  This value would have to be determined at the server before any
client side code has run, so this value could not be modified by the client.

for example if the varaible 'live' on the server contains 4, then the
javascript that is received by the client would say

document.all[LAB4].disabled = false;

The value is now stuck in there - it is not something that can be modified
by anything in the client.

Also, shouldn't this work in IE4 (if one wants to avoid eval):

document.all[LAB<%=live%>].disabled = false;

I think its pretty much unique to javascript.  The current recommendation is
to use getElementById() rather than eval(), but that will only work in IE5+
and NS6+

document.getElementById("LAB"+installNum)

guys thanks, the eval() worked a treat in all my years of programming c++, 
Java, VBScript and to a lesser extent Javascript I have never stumbled on 
it before.

Robert FYI LAB3 is a checkbox and we currently target IE4 and above.

cheers again
