There could be many things going wrong so we need to know a bit more about your setup.
The obvious one is 'does the GO user have permission to go to that layout?
Also, check the layout you are going to that it doesn't have script trigger scripts which return you to the layout you were on if you are on GO.
Also... I expect you have created a button then assigned a button function to it which was Go to Layout and then you selected the layout by name from the list. Is that the situation?
Thanks for your reply.
When generating the layouts, the first two I had changed to classic format, but the ones after that were still set as a different theme.
A quick update on the style to classic and working perfectly.
