If you try to just combine two categories for the GDNet dictionary without specifying a term to search for ( I was interested, so I tried it ), you'd get this error:
Microsoft VBScript runtime error '800a000d'
Type mismatch: '[string: "7, 9"]'
/adcode/adtop.inc, line 13
I decided to report this because I'm sure you'd rather have a big banner or something saying " Not possible " or something up than a nie little runtime error.
