What is the field type you are calculating from to? The value of the record you are trying to input from OBJECTID 3 will not fit the type of the field you are calculating to. Example would be if you are trying to put a Long type in a Short type field.
I realized what I was doing wrong. In this GDB that field is coded in the domains of the subtype as a numeric code no a txt code. When I put in the number it worked. Thanks for your help. When you asked what the field type was I realized what I had done.
