Dependency menus not working in edit page if the fields are blank

I have an application where a client side module addes new projects. The admin side then edits the projects. There are a series of dependent selection menus. The problem that I discovered is that the edit page errors out if any of the selections are left blank when first added. The error is:
Microsoft VBScript runtime error '800a005e'
Invalid use of Null: 'cstr'
/admin/include/commonfunctions.asp, line 1200
Line 1200 is if (CStr(value)="" or vartype(value)=11 and CStr(value)="False"
This has put me in a major bind because I was not expecting this error. Please advise as soon as possible.

Hi,
it's difficult to tell you what's happening without seeing actual files.
Please publish your project on Demo Account and send to support@xlinesoft.com a URL to your pages along with instructions on reproducing this error.

I'll find what's wrong with your project inspecting it at Demo account site.

Thanks for the assist. However, I had to move forward and found that, instead of using the dependency menus for edit, I can have the first menu used as the display for the others. Unfortunately, I overwrote the original files. I should have saved them but was in a hurry. When I can, I will duplicate the issue. If anyone wants to explore this issue, the problem arose when there are multiple dependency menu groups, let's say A, B and C. On the add form, the user makes selections for A and B but does not make a selection in the C group. Then, when I try to edit the entry, The error shown in my initial post occurs. I figured out that it was the blank dependency menus by changing the fields for group C to text fields. The edit page would then load.
