@acer That's perfect, thank you

@Joe Riel I wanted to display 3030

@Joe Riel I wanted to display the result of 3000*e^0.01 

@acer I'm sorry, I thought that I had to open another thread.

Anyway the data would be something like 3000*e^0.01, is my code wrong? 

Thank you both, now I know what I was doing wrong!
