You can learn how to do this exercise if you attend one of more of the courses listed below!
You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Open the file in the folder above.
Apply validation to the cost escalator so that it shows up as follows when you click on it:
Use the Input Message tab of the data validation dialog box to achieve this
And like this when you enter an escalator less than 10% or more than 400%:
Be careful to use your limits as between 0.1 and 4, since this is a percentage
Apply validation to the first 5 years of the ticket sales row so that the following warning appears if a user enters any ticket sales in these cells:
This is a warning only, so a user can choose to ignore it
Use the tool on the Home tab shown below to highlight all cells to which you have applied validation:
Click on this tool and choose Data Validation
Finally, apply protection to your model so that a user can only change the input cells (you will need first to check that your input style(s) are correctly set up).
Save the model with the same name, then close it down.
