[TYPO3] A small typoScript problem

[Brian Bendtsen]

Hi

I have a news plugin in my TS setup like this:

lib.importantNews < plugin.tt_news
lib.importantNews {
code >
code = latest
pid_list >
pid_list = 16
latestLimit = 1
templateFile = fileadmin/templates/tt_news_v2_template.html
singlePid =
categoryMode = 2
categorySelection = 6
}

I want to be able to give a non-admin user permission to change the 
categorySelection number.

Now, as far as I know a non-admin user cant access the TS setup, so Im 
working on a workaround. I thought I could do something like this:

temp.10 = TEXT
temp.10.data = subtitle
categorySelection < temp.10

and then the user could type in the number in the subtitle field(or a 
new field I will create) in the page header.

But this does not work. Im thinking it has something to do with the fact 
that the categorySelection property expects an integer and the subtitle 
is a string, but im not sure how or if its possible to convert it.

Maybe there is a more clever way to do what I want, any comment is welcome.
