Zoho global variables or workaround for that -

i'm new zoho crm. need show warning on button press once first button press. sounds simple yet can't figure out how in zoho creator variables seems have local scope can't determine if button pressed before. i've been searching if there global variables in zoho found workarounds creating applications case.

i've tried creating field on form , hiding pass value there if button pressed next time can check field not working reason.

in validation part i'm assigning new value field

warning_shown=true; 

but on form checkbox remains unchecked , next time press button warning_shown equals false.

any suggestions appreciated!

in case interested, here reply got on forum might help. here link topic

it's not going possible use validation code section display message.

i thinking have hidden decision box field, , in "on user input" of last field in form use like:

//remember change field names accordingly if !input.warning_shown {       alert "message here!";       input.warning_shown = true; } 

this show message after last field filled before button clicked.
