Not sure whether =IF function is the correct on to use, but I need to
test on values in column A, to see if the value is 1500 more (+) or less

column C, so that if the result is "true" then a number "3" can be
attributed for coding purposes

Please find an example of the data below;
A B
97081 21082

You need to more clearly state your requirements.
Is what you want to compare the values in the same row of column A & B?
In other words, do you want to compare only A1:B1 when putting a result in C1?
Or did you have something else in mind.

Also, you write you want to test if "1500 more (+) or less (-)".
Do you mean that the value in A is 1500 more than the value in Col B, or that the value in A is less than the value in colB?

In addition to the above, one interpretation would be that you want to test if there is a difference of 1500 between the values on the corresponding rows in col a and col b
Another interpretation, is there a difference of 1500 or more between the values.

If the last is what you really want, the formula would be:

=IF(ABS(A1-B1)=1500,3,"")

If you want something else, try to explain more clearly.
