How can I query 'between' numeric data on a not numeric field?

Question

I\'ve got a query that I\'ve just found in the database that is failing causing a report to fall over. The basic gist of the query:

Select *
From table

Use a CASE statement.

declare @StartRange int
declare @EndRange int

set @StartRange = 1
set @EndRange = 3

select *
from TestData
WHERE Case WHEN ISNUMERIC(Value) = 0 THEN 0
            WHEN Value IS NULL THEN 0
            WHEN Value = '' THEN 0
            WHEN CONVERT(int, Value) BETWEEN @StartRange AND @EndRange THEN 1
            END = 1
