Creating globals on the fly

Hi all,
It's getting late, so I'm probably missing something obvious.
I'm trying to write a set of generic handlers that fetches and replaces data from a global variable that contains its data in a table (or array, if they're the same thing - not sure of the nomenclature here!). The reason I'm not working with variables directly is because in the future, I might want to swap saved files with a database. Plus, it's easier to save a few of these master variables to a file and clean out them out when the user loads in a new file.
Anyways, when the variable hasn't been created, the handler works: it creates the new global variable and puts the required data into it. Lovely.
Problem is, when I then try to use the handler to add a second line or replace theElements of the first, it creates an entirely new global varible with a name of the data I stuck in the correct global variable.
Any help gratefully received!
Steve

on writeToTable whichTable, whichKey, whichCase, theElements
do "global " & whichTable
do "put " & whichTable && "into tempTable"
set itemDelimiter to numToChar(28)
put lineOffset (whichKey & "_" & whichCase, tempTable) into theLine
if theLine> 0 then
put theElements into item 4 of line theLine of tempTable
else
put whichKey&"_"&whichCase into line (number of lines of tempTable) + 1 of tempTable
put whichKey into item 2 of last line of tempTable
put whichCase into item 3 of last line of tempTable
put theElements into item 4 of last line of tempTable
end if
do "put tempTable into" && whichTable
end writeToTable
