touble with a time calculation

[longpole001]

ok well EL0 is counting up , EL1 and EL3 are copys of EL0
EL4 is the time left in the event

Event1_OT = time duration of event
Event2_OT = Time when to display the timeleft clock
i
f EVent1_OT all 0 then disable time left clock
if Event2_OT all 0 then no timeleft clock

Event2_OT can not be > Event1_OT set time

 if  Event1_OT_Day = 0 and Event1_OT_hour  = 0 and Event1_OT_Min = 0 and _            ' if all values are 0 , then dont enable the overrun timer 
        Event1_OT_sec = 0 and Event1_OT_100th = 0 then 
          EL2_Enable = 0 ' Disable El2 Counter   
          EL2_Allow = 0  ' clear Flag so EL4 wont start   
    else
          EL2_Allow = 1  ' Event1 setting Higher than 0 so allow EL4 to be enabled if Event2 settings are higher than 0 
    endif
    

' ---------------------

 if  Event2_OT_Day = 0 and Event2_OT_hour  = 0 and Event2_OT_Min = 0 and _  
       Event2_OT_sec = 0 and Event2_OT_100th = 0 then 
         EL4_Allow = 0  ' disable Event End Timer - EL4 
   else
         EL4_Allow = 1  ' Allow Event End Timer - EL4 
   endif 
   if EL2_Allow = 1 and EL4_Allow = 1 then                        ' if Event1 times set and Event2 times set then allow EL4_enable to start Event End timer 
      
       if EL1_Days    <= Event2_OT_Day and EL1_Hours   <= Event2_OT_Hour and _
          EL1_Minutes <= Event2_OT_Min and EL1_Seconds <= Event2_OT_Sec  and _
          EL1_100th   <= Event2_OT_100th then EL4_Enable = 1                                ' show clock when time left in event

all i have so far
