Filter Table With Greater than, Less Than Formula

Hi

I need to create a filer on a report to will allow the user to dynamically filter an animal table based on animal age in months with greater than less than. Eg show me animals aged between 1 and 36 months

I have the age of animal age in months, my issue is that I don't know how to create a filter that will give me a list of the animals that match the filter criteria

Here is a demo of data I want to filter:

RAW TABLE DATA:

CLIENTID ANIMALID    AGE(MTHS)
client 1     animal 1         12
client 1     animal 2         15
client 2     animal 3         13
client 2     animal 4         19

END USER FILTER:
Age(mths) >= 12 and Age(mths) <= 14

END RESULT:

CLIENTID  ANIMALID    AGE(MTHS)
client 1     animal 1        12
client 2 animal 3            13

To Surmise I need a way to filter the data based on a greater than less than and a way for the user to select these parameters from a filter on the report

Thanks for any help, it is much appreciated
