I am having a problem with a form that has check boxes on it. If several checkboxes are checked it works great. If only one is checked then it gives the following error:

Traceback (innermost last): File lib/python/OFS/DTMLMethod.py, line 151, in __call__ (Object: editmanystatus.dtml) File lib/python/DocumentTemplate/DT_String.py, line 513, in __call__ (Object: editmanystatus.dtml) File lib/python/DocumentTemplate/DT_In.py, line 628, in renderwob (Object: nums) InError: Strings are not allowed as input to the in tag.

I can see that it is because instead of a list it now has a single string but I don't know how to handle this. Is there a way to force an object to be a list whether it is a list or a single string?

Yes. In your form, give the name a :list suffix: <input type=checkbox name="nums:list"> This forces creation of a list even if there is only one value.
