Module 4.8.2

Hello, I am new to the Mendix community and have recently started the rapid developer learning path. I found myself getting stuck with creating a new page for the Training events. This occurs in module 4 at section 4.8.2. Anytime I try to add an extra column to the layout it is not the same size as the ones made previously. I’m pretty I might be doing something wrong, but I’m just not sure. I have looked back at Module 3 as instructed, but I didn’t find anything about making a fifth column. Any feedback would be helpful.

DoubleClick the header of the new layout column, that will make a popup show up where you can change the width of the column. Make sure that the total width of all columns combined is 12. This because Bootstrap needs a total of 12 to get the layout right.
