multiple countdown timers are delaying!

[Lamn]

Hi,

I have created 2 simple countdown timers on an excel sheet, however when both (1 alone works fine) are working simultaneously the time starts delaying. What happens is that it takes more than 1 second of time for the timer to drop 1 second, meaning that if for example I set 10 mins of countdown, the timer will reach its conclusion after about 11 mins instead of the pretended 10 mins.

Anyone knows how to solve this issue?
Thanks

This is a common problem when encountering multiple timers.
It is dependent on the method adopted - the timers can interfere with each other and delay or speed up each other.
It would be easier to offer the right solution if you post your workbook.

Code placed in sheet module - time period in seconds in green box - then press start.
Similar app also attached for reference if you need to get more complicated.
