Thanks for your replies!
@sahi JS returns msg with a string ("cancel") or with information about the selected items. To use the JS array I had to convert it to a Ruby array. So I used the split method.
@driven. I think I understand the problem. I unfortunately have not enough experience/knowledge to rewrite the JS part so Ruby can understand it. So I think I'll use the separate html file and wb.set_file method.
Thank you for your replies!

Thanks Sahi for your quick reply!
I removed the <meta>-tag and contents. Still the same problem.
Still the webdialog.Set_file works, the webdialog.set_html doesn't.
I get this error from the console:
Error: #<NameError: undefined local variable or method wb' for main:Object> C:/Program Files/Google/Google SketchUp 8/Plugins/mbl.rb:149:in mbl_main'
C:/Program Files/Google/Google SketchUp 8/Plugins/mbl.rb:186
I can't find the variable. I do not understand why this error is reported with the same html file/string?
Please help, thanks in advance!

Hi All,
I'm a complete newbie to Ruby and programming for Sketchup. I use Autocad and Sketchup to model my models. I saw some great plugins to assign materials to layers. (Useful when you work in both Autocad and Sketchup). Still I wanted to write my own plugin and learn Ruby by combining a lot of snippets from different, brilliant plugins.
So this is my problem. When I use webdialog.set_file ('somehtml.html') everything runs smooth. But when I add a variable e.g. htmlstr = "here I put all the contents from the somehtml.html file" and use webdialog.set_html I get an error.
I tried several things but nothing seems to work. Please help me. What am I doing wrong?
Thank you!
Jeroen
I added the script:
The info assigned to html variable is the same as the info from the mbl.html file used in the wb.set_file command. Therefore I did not add the HTML file.
