Hi

I have entered a time value 27:00 in cell A1, with the following custom
format [h]:mm:ss. I want to construct a test that will
return "True" if the A1 is more than or equal to 24 hours, and "False" if
less than 24 hours. I know this will entail the use of the
"IF" function, which I've tried but cannot get it to compute the correct
response. Hope somebody can help with this.

Kind Regards - Grant
