Displaying variables

[Greg Hains]

Hi.

Im looking to display variables directly onto the screen somehow. I was thinking of putting these variables (get(accountname) etc) into a field, but as the user is multi-user it would not work correctly as each user would override it.

How can I schieve this please?

Cheers,

Greg

If you have FMP Advanced you can see variables in the data viewer.

Variables are like global fields; each user has their own values anyway. But Get( AccountName ) isn't a variable; it's a function. It should change for each user.

Hi Vaughan,

Thanks for the reply.

I do use the data viewer for debugging and what-not, but need to display some of these variables on the screen for the user for current login name, and other basic system info. I dont think they should have to go into the data viewer.

No way of displaying them as part of a layout?

An unstored calculation field would work fine.

Try it and see.

Hi DJ.

Ok, I'll give that a whirl. Its just the multiuser bit that worries me a bit, but I suppose if it's unstored it shouldnt matter.

Thanks,

Greg

Calculations that use the Get() functions *must* be unstored to work correctly, otherwise their value is never updated.

Hi Vaughan,

You kind of broadstroked that, didn't you.

Either an unstored calculation field or a global field set by the opening script should work fine. The global field has the advantage of being accessible from unrelated TO's, so you can place it on any layout.
