Adding to a string

With narkets that meet a certain criteria I wish to build a single string that is made up of all their start times.
To do this I can set up the first one by setting a global variable, myvar, to event_off_timestr.
As it is triggered on other races how can I had further time strings? Is it something like setting myvar to myvar&event_off_timestr?
Thanks

Hello!

Unfortunately, MF Pro does not have a built-in string concatenation operator.

But the attached construction will work nonetheless, as MF Pro will parse the variables inside the string and assign it to myvar.

This is working well.
Every evening I load new markets at 2145 and activate them all.  I have a trigger which deletes all but the ones that meet certain criteria which are the ones that get added to this string.

Obviously this trigger will only fire once unless I reload triggers so I have created another trigger in a separate block to close this block so it will re-fire.

However it doesn't seem to be working and, although the log shows the block being closed, the trigger continues to run on past this point.

Any ideas what I am doing wrong?

Thanks

Hello!

although the log shows the block being closed, the trigger continues to run on past this point

Of course the trigger continues to run: once the block is closed, it essentially "forgets" that any of its triggers have ever been executed, including the one that closed it, and all starts anew.

What behavior did you expect instead? Do you need the closing trigger to work only once?
