I need to create a url with Concat function, but also I need to add to this link additional parameters set in the email properties. Therefore, I placed the URL not in the AMPscript block, but in the a tag.
This is my try:
%%[ VAR @url, @subscriber_key, @jobid SET @subscriber_key = _SubscriberKey SET @jobid = JobID ]%%
Unluckily, it doesn't work: sending a preview and clicking on the resulting link, I receive the horrible error message "bad request - invalid url".
Where am I wrong? Thank you, G.
