title: How to use "or" in Excel Solver constraint
body: <p>I am adding a constraint to Excel Solver.</p>
  
  <p>The constraint is saying an input data at location A3 must be either 0 or between 3 and 8.</p>
  
  <p>How could I add this constraint in Excel Solver since I could not find 'or' function in solver constraint box. It only has ">=", "&lt;=", "=", "int", "bin", "dif" operators there.</p>
  
  <p>Many Thanks</p>
