Hi,

I have no problem with your SmartPart.
By clicking at "+" the value of "test" is increased.
But if you want to use "test" in the script, the it can fail! Why?
"test" without anything inside a script means always the VARIABLE "test".
You have only access to PARAMETER-values with "PARAMETERS"-Command!
Each PARAMETER is copied into a variable at beginning of each script execution.

So in your script PARAMETER "test" is modified, but the VARIABLE "test" not!
It's important to modify the PARMETER and VARIABLE synchronously by

test=test+1
PARAMETERS test=test

Another problem can be, that Parameter-Script is executed more than one time!
If the IF-criteria matches, then test can incresed twice!
(The GLOB_UI_BUTTON_ID goes to "0" after a parameter-script execution!)

The reason for this error is the following setting being activated: auto-update based on value list, which,personally,I don't know what is used for. This happened since a allplan 2012 update for smartpart (which was made to solve some problems with smartparts inserted in doors or windows).

Hi,

the behaviour was indeed an error in 2012. It rises only, when the mentioned option was activated.
The setting has the following benefit:
If you have a little script like this (see grid_script.png) for rasterization of length values.
After changing the grid space from "0.001" to "0.1" , it can be, that some values become invalid
(e.g. ref_x = 1.123)
With activated option "Auto-Update based on value list", these values are corrected, so that they match the limits from VALUES-Command (see option.png).

Regards.
