HELP! Search all the numbers in between +/- input number and return all results

Hello!

Example:

I tried to do it on my own, but it's just not working. The logic is to type wanted decimal number in "user input", search for that number in column D and return all the matching values from column C. The input has to be calculated inside limit (in my case it's +/- 0,03), so the result must return all the values from column C that are inside limits.

Example:

Input: 8,00 +/- 0,03
Search range: 8,03 to 7,97
Search for all numbers in that range in column D
And then return all values from column C in that range.

Thank you!
