Hello Mohd.

I guess you could have picked a simpler derivation to do the "test" on ;-)

Without seeing the entire "Image" here, I can only surmise that what you want is to figure out how long the process took.

The easiest way is simply to set the time in a global variable at the start.

SetVar("Timer",CurrentTime)+etc,

Then at the end if you want to set the result in a label you can simply add.

+SetLabelText("update opening",current time-GetVar("Timer"))

This will set the time in seconds.

On a different note.

,concat(LabelExecDQL(timer2)+

What are you trying to do here. LabelExecDQL execute the DQL in a label named either in "" or via a field value etc. Here you reference a field with a time in it...?
