Here is my WEB page on my side which does not work correctly:
this is the error I get; which is highlighted in my code near the bottom in yellow.
Unhandled exception at line 157, column 17 in Crafts.aspx
0x800a138f - JavaScript runtime error: Unable to get property 'style' of undefined or null reference
-------
I am using Visual Studio to create the site. I am verse VS.VB and like the IDE plus, I know how to connect to SQL using it and so on.
Any ideas like what I am missing?
