Change parameter with button

[Anonymous]

Hallo, I want to increase (or reduce) parameter with button on UI page. But when I push the button, parameter increased for +2 but I want just +1. I posted attachment. Where is the problem?

You never know how much the Parameter Script ist run.
My suggestion:
Create 2 new parameters for the Buttons
and write in the PARAMETER Script
IF GLOB_MODPAR_NAME = "thisParameter1" THEN
...
ENDIF
IF GLOB_MODPAR_NAME = "thisParameter2" THEN
...
ENDIF
