I'm experiencing the same error with Dynamic Dropdowns 2.74 (never happened in 2.73). I install the extension. As soon as I make a selection to create a new Dynamic Dropdown array, I receive the message,
At line 22 of file "C:\Program Files\Adobe Dreamweaver CS4\Configuration\ServerBehaviors\ASP_VBS\WA Dynamic Dropdowns\Create Dynamic Array.js: WA_checkMySerialNumber is not defined."
I have gone through all the requested ideas in both CS3 and CS4 to get this working and get the same error every time.
What can be done to resolve this issue? Can I try 2.73 which was overwritten? Was there a resolution or are users still experiencing this issue?
