Sorry if this seems a bit stupid - I'm a super neewbie.

I'm trying to make a script for a 'back' button that will take the user back to the layout they just came from. I can't specify the destination layout explicitly because the layout with the 'back' button can be accessed from several locations.

Any help would be much appreciated.

Hi Jimbo and welcome

Set up a global field - 'G_Lastlayout'

Whenever you move out of a layout perform a script that has one line

Setfield [G_Lastlayout;Get(LayoutNumber)]

Attach a script to your 'back' button also with 1 line

Go to layout(G_LastLayout)

and specify layout number by calculation (bottom r/h/s of script window) when you specify this step

Hey presto! your back button will always take the user back to wherever they came from

A slightly fancier version of what Phil said is to use the global field as a stack so that you can back up many levels like in a web browser. When you go to a new layout, set your global like this:

Setfield [G_Lastlayout;Get(LayoutNumber) & ¶ & G_Lastlayout]

When you click the back button, it performs this 2 line script:

Go to layout(LeftValues(G_LastLayout;1))

Setfield [G_Lastlayout;MiddleValues( G_Lastlayout;2;99999)]

Hi guys,

Thanks for the help, and the warm welcome.

I've implemented Phil's suggestion and it worked a treat. I even had a rough idea of what I was doing!

Bob's 'multiple backs' solution looks cool, but I think I'll walk for a bit before I try running. :

Something for the To Do list.

Cheers

Jim
