Variables suddenly lose their set values

Why would variables suddenly lose their values when  form loads?  I have a variable that I set to 'true' when the form loads... and I check it at different stages using a message box.  It remains 'true' all the way through the code.   The variable is then used in the after_update of a textbox... when I put a value in the textbox, the variable is gone... somehow it is getting wiped and I can't figure out why...  other ones (global) that are either set on previous forms also disappear.   This was all working up until yesterday...so it has to be something I did yesterday, but I am at a loss as to what it could be.

Are there any certain things I should check that might cause variables to lose their values suddenly?


Thanks

Did you add a "Stop" statement anywhere in your code recently?  That causes all globals to be lost.

Actually, Stop does not clear variables:

From Help:
"The Stop statement suspends execution, but unlike End, it doesn't close any files or clear variables, unless it is in a compiled executable (.exe) file."

Where are this Globals located?  In a vba module? Form module?

Also ... does you code compile?

Are any errors occurring ... and then End is being hit?  End will clear variables.

What does it mean to be "Always On"?

No stop  and the globals are in a vba module.

The code does compile.

Can you single step through the code .. .from the point where the variable is set ... to where it's gone?

Do you have any code that deals with forms in design view?

That *might* affect your globals..

Just hazarding some wild guesses here, but we may be able to come up with something more concrete if you post your database (with any sensitive data masked or removed, please :) )

I would post it but the .mdb is only a front end, the entire be is SQL.

You already have this right

?

If not, get it ... and then search for all occurrences of that variable ...

Thanks, I'll get it because I am sure it is helpful...but in this case it is all variables that were previously set that are getting wiped..
