title: How to implement if statement to Excel Solver
body: <p>I want a variable to be either 0 or greater than 3 in excel on my production planning design with solver. Is this possible?</p>
  
  <p>I have tried using IF statements as in if x is not zero then its going to be subject to =>3 constraint otherwise there is going to be a random big number on the LHS of the constraint to avoid it. This method gave an infeasable solution.</p>
  
  <p>Thanks in advance!</p>
