trigger = system.tag.readBlocking(["[CC\_OEE]TrumpfTags/2267/TruLaser (L52)\_A1230E0148/Machine/Flag"])[0].value  
date = system.tag.readBlocking(["[CC\_OEE]TrumpfTags/2267/TruLaser (L52)\_A1230E0148/Machine/endtime"])[0].value  
if trigger == bool(1) :   
id = system.db.runNamedQuery(“Enterprise/site specifique/pull”,{“date”:date})  
start=system.db.runNamedQuery(“Enterprise/site specifique/debut”,{“id”:id})  
end= system.db.runNamedQuery(“Enterprise/site specifique/fin”,{“id”:id})  
system.nav.openWindowInstance(“SiteSpecific/fault description”,{arret:id,debut:start,fin:end})  
system.nav.centerWindow(“SiteSpecific/fault description”)

When asking questions like this where you are shoing code, you can format the block by highlighting it and, and pressing the ‘Preformatted Text’ button (looks like `</>`)

```python
trigger = system.tag.readBlocking(["[CC_OEE]TrumpfTags/2267/TruLaser (L52)_A1230E0148/Machine/Flag"])[0].value
date = system.tag.readBlocking(["[CC_OEE]TrumpfTags/2267/TruLaser (L52)_A1230E0148/Machine/endtime"])[0].value
if trigger == bool(1) :
id = system.db.runNamdQuery("Enterprise/site specifique/pull",{"date":date})
start=system.db.runNamdQuery("Enterprise/site specifique/debut",{"id":id})
end= system.db.runNamdQuery("Enterprise/site specifique/fin",{"id":id})
system.nav.openWindowInstance("SiteSpecific/fault description",{arret:id,debut:start,fin:end})
system.nav.centerWindow("SiteSpecific/fault description")

```

You can open the diagnostics either through the help menu or Ctrl+Shift+F7

That said, you need quotes around arret, debut and fin parameter names on the openWindowInstance() line
