[TYPO3] Tip a friend - problem - ERROR: malformed or missing URL detected!

[Morten Kjems]

Hi.

I have installed the Tip-a-Friend extension and followed the tutorial.

The TIPLINK links correcly to the TIPFORM but the TIPFORM displays an 
error message:

"malformed or missing URL detected!"

If I submit the form nothing happens...

I simply have no clue on how to solve this.

Any suggestions?

Thanks
