[TYPO3-english] Condition to know if a variable is defined inthe URL

[Stephen Bungert]

Try something like this:

value.data = GPvar:tx_ttnews|news

Just change the variable name to your extension
so

value.data = GPvar:tx_ext|myVar

Yes. I have to go with the first option. It works ok, but it means I cant
give them negative values. still it works :)

I know its a little off-topic with the subject but, how can I set the value
of the variable to a TEXT object? value.data = ???
