Write a python program which takes in a range of numbers (2 numbers, both included) from user input and prints all the numbers divisible by 7 and multiple of 5 in that range.

Include a warning message in this code for when the values entered won't be divisible by 7 or give multiple of 5.

Example:

User input: 2000, 2500

Output: 2030,2065,2100,2135,2170,2205,2240,2275,2310,2345,2380,2415,2450,2485
