Simple Value Selector

Hi,

I have a field that uses Simple Value Selector. When I check the SVS drop down, It has 2 names Tom and Mark.

If I do not want to put any of these 2 names in that Input field, but instead put Mike in the field, it throws me the following error.

<b>String "MIKE " does not match the enumeration</b>

Is it possible in an input field associated to SVS, if I do not see a value in the SVS that I want to use. Can I input a new Value in the Input field without getting the above error.

Any help would be appreciated.

Thank you.
