I have a Gateway Event Script Set to run twice a Day. Is there a way to manually force this script to run by user input without having a second copy of the script? What I want is for the script to run twice a day or whatever I set the schedule for, but also to run a single time with user input (button click), but not have the script in 2 different places. ---

Put the logic in a project script. Then call the project script from the gateway event to invoke it on your twice-a-day schedule or from a button when needed on-demand. ---

> [@dkhayes117](#): > > Put the logic in a project script. This, always. While you **can** write entire scripts in the dialog for your event, you should not. For best maintainability, and for other uses, event scripts should be one-liners that just pass all the relevant event information to a project library script. ---

I have the script put in project library and Scheduled event to call it. If I want a button to call it would the best way be to screen button --\> changes tag [RunXScriptTag] then have gateway tag change script monitor [RunXScriptTag] to call the function instead of having the screen button calling the function directly? ---

No, if you go through a tag, then your clients aren't independent. Just call the script from the button. ---

> [@pturmel](#): > > t inde I tried that at first but it locked up the client. Script is quite large, checking a DB table against tag values and correcting if needed. Takes about 2 min to run if no changes and can be much longer if it finds and corrects errors. I don't need more then 1 client to run it at any time. This is an administration level operation so the "button" would be restricted access and rarely used. ---

Or `system.util.sendMessage` to run it on the gateway. Add some locking/exclusivity in the message handler before actually invoking the slow code.
