I have a problem with publishing in SDL Tridion 2009 web site managament. When I am publishing the Master page (in order to publish all the subfolder elements) it shows a failed status in the publishing queue.
The pages seems to be successfully published but the master page is failed, so the changes of the pages doesnt appear on the website. The context of the problem is:
JScriptException: Expression 'GetImageAlt("tcm:70-1386")' had error 'Variable 'GetImageAlt' has not been declared'.
The TCM address in the error message, is from our corporation logo. What should I do to fix this problem and publish successfully?
