HI, Can someone PLEASE HELP!!!!!!!!!!!!!!!!!

I am using the following count to count how many time a number above 70
is
input, I need to add M or F onto the end of the numbers. e.g. 74M, the
formula i'm using does not recognise both number and text.

this is the formula i'm using: =COUNTIF(Interventions!C19:C81,"70")

I need to add a letter M and F onto the end of this formula to
recognise
input of e.g. 74M, 86M, 95F to place in correct cells on a different
worksheet.

70+ Males for M & 70+ Females for F

I have cells with headings Male 0-5 6-15 16-30 30-70 70+ the same for female
and age ranges these are against medicines.

So e.g. I want to input 56M into a cell I want this to count up into cell
labeled Male 30-70 and so on, keep counting the number of times ranges are
entered to M or F the same if I enter 74F I want this to count in the cell
labelled Female 70+.

Hope you can understand this, thanks for the HELP!!!!!
