Hi @Momentum ,
Sorry you're having problems with the Transpose functionality. Without knowing exactly what you're trying to transpose, it's hard to pinpoint what is the specific solution to your problem. More context would be needed for your specific case.
There could be a few different reasons why, but as an example, you can open the Big Class.jmp file from Help > Sample Index. Then, if you select the columns :age through :weight and try to transpose that, it won't work. In this case, the reason is because the column :sex is a nominal data type, i.e. text. Since you can't have columns with different data types in them continuous and nominal, JMP won't perform the transform. If you remove :sex from the transpose column list, you'll get the transpose you expected.
As you become more familiar with JMP, you'll hopefully start to use the JMP Scripting Language (JSL) to automate tasks, and when you do, you'll likely reach back out to the community for help when you're stuck scripting. Using the <JSL> to add JSL will format the added JSL code as you would see it in the Scripting Editor, it just helps with reading other people's code when they post it to the community.
The @ symbol is useful for just that: linking to members, e.g. "mentioning" members, or to linking to other content. As soon as you type the @ symbol a popup window allows you to link to members or content as you desire.
Hope this helps, and welcome to the community if you are new!,
