Count Occurrences In Worksheet Based On Data In Another Cell

I have my workbook set up so that one worksheet contains the names of all my departments/sections listed with their 3 letter code (this can be anything from AAA-ZZZ, e.g 'FYH', 'JWK' or 'KZA' are all valid) in Column F. I then have Columns H, I, J & K blank and require them to be auto-filling based on data from 4 other worksheets - i'll detail what i need below, but Column H needs to be filled based on what it finds in worksheet 'Data 1', Column I should be filled based on what it finds in worksheet 'Data 2' etc. etc. I have four further worksheets that contain data based on the types of assets owned by the department/section, these are 'Data 1', 'Data 2', 'Data 3' and 'Data 4' and I use these as described above, with Column H referring only to 'Data 1', Column I only to 'Data 2', Column J only to 'Data 3' and Column K only to 'Data 4'.

What i need then, is a VBA that will take the value of a cell in column F on my main worksheet (called 'main') and then count the number of occurences of that value in Coulumn A on another worksheet and place the number of occurences into Column H, I, J or K based on which sheet it's checking.

For example, Cell 'F2' on my main worksheet contains the value "ABC". I need to take "ABC" and search Column A of worksheet "Data 1" to find how many time it occurs, placing the result into Column H of worksheet 'Main', I then need the same value to be counted in Column A of 'Data 2' and its result placed into Column I on 'Main', and again for Column A of 'Data 3' with the result being put into Column J of 'Main', and finally Column A of 'Data 4' to be checked and that result placed into Column K on 'Main'.

does this seem too much of a task for VBA? or am i best doing each column separately with a CountIf or Array formula?? Not sure whether a COUNTIF or Array formula will do the job.
