Send Message alert for a time field

Question

Hello,
I have a finish time field in a memorandum agenda form which I would like an alert (message) sent 2 minutes before the finish time expires.
The script has an error message for the "," on line 4.
var vEnd = Time2Num(ActionsEndTime.formattedValue, "HH:MM") // this is the finish time
var vSec = 2 * 60 * 1000  // time in milliseconds - which is 2 minutes
var vFinish = vEnd - vSec // take away the finish time from 2 minutes to give a new time to trigger to alert
var vcurrent =  form1.ActionsHeaderFrame.DateTimeField1.formattedValue, "HH:MM") // this is the current time field
form1.ActionsHeaderFrame.DateTimeField1.execCalculate() // recalculate a hidden current time field to give the current time
if vcurrent = Num2Time(vFinish, "HH:MM") then  // if the current time equals the finish time - 2 minutes then show message
xfa.host.messageBox("You only have 2 minutes to finish the agenda " ,"Reminder",3,0)
else
endif
Can anyone please advise where the formcalc script needs correcting?
Any assistance will be most appreciated

Thank you for your reply.
I have modified the script as you have suggested:
var vEnd = Time2Num(ActionsEndTime.formattedValue, "HH:MM") // this is the finish time
var vSec = 2 * 60 * 1000  // time in milliseconds - which is 2 minutes
var vFinish = vEnd - vSec // take away the finish time from 2 minutes to give a new time to trigger to alert
var vcurrent =  Time2Num(DateTimeField1.formattedValue, "HH:MM") // this is the current time field
form1.ActionsHeaderFrame.DateTimeField1.execCalculate() // recalculate a hidden current time field to give the current time
if (vcurrent == Num2Time(vFinish, "HH:MM")) then  // if the current time equals the finish time - 2 minutes then show message
xfa.host.messageBox("You only have 2 minutes to finish the agenda " ,"Reminder",3,0)
else
endif
I need help with recalculating the current time field as the execCalculate() will update once and remain static.
This is the function in the current time field for the current time  -  DateTimeField1.rawValue = num2time(Time(), TimeFmt(1))
Is there a way to have the time field show like a system clock time and refresh automatically?
I think this will be the only way I can get the formcalc script to work the way it should.
Any suggestions you may have will be most appreciated.
