I would like to start with my coding ability is very limited. With that said I have scoured the internet for the last couple days mulling over previous VBA codes looking for something that will meet my needs. But unfortunately my search has resulted in nothing that I seen would give the results i am looking for. I am needing a count down timer that will initiate when the time is keyed into a certain cell. The timer will always countdown from 24 hours. Hours and minutes are the only two parts of data I need if that makes it easier. Also I would like to have an audible alarm loop once the timer is null until either a box is clicked or check box is clicked to acknowledge the timer has ended. To give an idea of the data this is for samples taken and must be checked 24 hrs after time that is put into the spreadsheet. This same spreadsheet will be used for revolving data through an entire year so the total entries could exceed 1,000 but should not exceed 2,000. I have read in my search how many entries may result in an inaccurate timer. Is this something that is possible to accomplish? Im not asking for someone to do the coding for me but hoping someone may be able to lead me in a direction to where I could compile a couple code variations together to get the result i'm looking for. This may be extremely simple to some but for me i am totally lost. Any help would be greatly appreciated. Thank you in advance.
