Building adjustable launch date timing into a forecast

[DanLam21]

Hi.

I'm building a model that allows you to adjust Data Validation lists to display different outputs.

This includes adjusting the Project name (A-D), the scenario based on risk (1-3), and then applies specific growth rates based on those inputs

I would like to make an adjustment that allows me to adjust the launch month (as seen in the table below in column C). If I were to adjust the month to "Jan", I want the formula to apply the 0.1% growth rate to all of 2018, however if I adjust it back to "Jun" I want the formula to automatically zero January-May and apply the growth rate in June and every month after that in 2018.
