A condition is a criteria that helps the spreadsheet make a decision. So if you had a list of exam results and you wanted to put the words Fail or Pass beside each result, based on the score, then your condition would be the pass mark. So if 40% was the pass mark, you condition would be whether it is greater than or equalled to 40% or not. The function would be something like this:
=IF(A1>=40%, "Pass","Fail")
The condition is the A1>=40% element.
No. The condition of a cell can be either true or false.
It could be an equation or an expression or a condition.
It is when you are using an OR condition, which in Excel can be implemented through an OR function, or in an Advanced Filter by listing the criteria on different rows.
It will if you are asking about conditional formatting.
And
Use data validation and require a specific entry in the cell. See related links for various options for data validation in Excel.
Usually for excel documents I use other interesting programs, but one day I observed at the I-net a good tool, which to my great surprise solved out my old troubles with excel documents, indeed I hope the tool will help in this condition too.
IF function
The COUNTIF function can do that.
The question can not be answered without a detailed description of all features, markings, condition, etc..
Conditional Formatting.
The IF function has 3 parameters. The condition, the true part and the false part.
