Perfect, Brian. I do indeed have to save more than 2 items to each row. I was trying
ArrayDeleteAt but screwing up the syntax. Thanks very much for your help yesterday
and today nursemaiding me thru this.
In case its useful to anyone poking around in the archives some day, here's the
template I used to test the creation and deletion of 2d array items.
<cflock scope="APPLICATION" type="EXCLUSIVE" timeout="10">
<cfparam name="url.row" default="1">
<cfset client.UserID=url.Row>
<cfparam default="N" name="url.Delete">
<cfif not isdefined ("application.myArray")>
<cfset application.myArray=ArrayNew(2)>
</cfif>
<cfif url.Delete is "Y">
<cfloop
from="1"
to="#ArrayLen(application.myArray)#"
index="ArrayRows">
<cfif not Compare(application.myArray[ArrayRows][2],client.UserID)>
<cfset arrayDeleteAt(application.myArray,ArrayRows)>
<cfbreak>
</cfif>
</cfloop>
<cfelse>
<cfset start=ArrayLen(application.myArray)+1>
<cfset stop=ArrayLen(application.myArray)+1>
<cfloop from="#start#" to="#stop#" index="i">
<cfset application.myArray[i] = arrayNew(1)>
<cfset trash=arrayAppend(application.myArray[i],i)>
<cfset trash=arrayAppend(application.myArray[i],i)>
<cfset trash=arrayAppend(application.myArray[i],now())>
</cfloop>
</cfif>
<html><head><title></title></head><body>

<cfoutput>
<cfloop from="1" to="10" index="i">
<A href="#cgi.script_name#?Delete=Y&Row=#i#">del #i#</A>
</cfloop>
<A href="#cgi.script_name#">Plain</A>
</cfoutput>
<cfdump var="#application#" label="application variables">
</body></html>
</cflock>
