if you enclose your code snippets in <pre></pre> tags it improves their readability

Are you sure that this code is in the code file associated with the aspx page? ie. Does the CodeBehind attribute at the top of the aspx page point to the file you're trying to access the text box from?

One potential source of this problem is having two different .aspx files pointing to the same .aspx.vb file.

Another potential source is if you have copies in the same directory of the same .aspx and .aspx.vb files. For example you copied the files in windows explorer(copy of ... .aspx) to save your work as some point. Delete or move those copies out of the webapplication folders.

You could also try some of the steps in this post:

Forgive me, I don't work with ASP.Net often (which is the forum where this question SHOULD have gone!), but should that be ID="alma", or Name="alma"?
