Warning Alerts Depending On Time Remaining To Finish Task

[peter renton]

I have added the coding

The warning comes up at 30 mins to go but re occurs every minute, how do i get it to do one warning at 60min to go then one reminder at 30mins to go and an over due warning when it goes minus? also could it pick up the customer name in the warning so its easy to see which row the alert is for?

Selecting the completed seem to stop the alert but not the clock (do i need to put a code in w column?) also code it restart the clock if this is de selected.

Sorry if i am been a bit thick here but i am just trying to get my head around how the codeing works

Thank you for looking
