When a model "blows up" due to a circular reference which of the following is false?

• Doing "find and replace" on the entire model, finding = and replace with = will turn the model linear momentarily, allowing Excel to process necessary changes

• Selecting the circular formula, hitting delete and then CTRL Z is likely to work

• The model must be turned into a linear model to give Excel a chance to process necessary changes made

  Turning off iteration will fix the model
