conditional validation rules

I have set a validation rules for a table and also for fields.  Now I need
to 
set another table validation rule to say:
	If field1 = “complete”, then field2 must be greater than zero (it is
a 
numeric field).
	If field1 = “incomplete”, then field 2 can be blank or zero.

I have set a validation rule for field1 to either “complete” or
“incomplete” 
and made it a required field.  I want to make field2 a required field
also.

I am unsure of how to enter this into the table’s validation rule, or
even 
the field2 validation rule.  Do I just start another line and start typing
a 
second rule in VB mode for the table?  Or do I have to identify each 
validation rule?  I hope this makes sense.
