Find integer in a group of integers

BonusCup

Hi,  I'm trying to filter for records where the integer is found in a group of integers like below.

JSON_Name1	Concat_JSON_Name1	Filter
0	3,18,28,30,33,40,42,49,51,54,55,68,70,73,76,81,83,89,94,96,97,98,99,100	OUT
10	3,18,28,30,33,40,42,49,51,54,55,68,70,73,76,81,83,89,94,96,97,98,99,100	OUT
18	3,18,28,30,33,40,42,49,51,54,55,68,70,73,76,81,83,89,94,96,97,98,99,100	IN
32	3,18,28,30,33,40,42,49,51,54,55,68,70,73,76,81,83,89,94,96,97,98,99,100	OUT
42	3,18,28,30,33,40,42,49,51,54,55,68,70,73,76,81,83,89,94,96,97,98,99,100	IN
80	3,18,28,30,33,40,42,49,51,54,55,68,70,73,76,81,83,89,94,96,97,98,99,100	OUT
89	3,18,28,30,33,40,42,49,51,54,55,68,70,73,76,81,83,89,94,96,97,98,99,100	IN
101	3,18,28,30,33,40,42,49,51,54,55,68,70,73,76,81,83,89,94,96,97,98,99,100	OUT

I've tried Contains([Concat_JSON_Name1],[JSON_Name1]) but everything still comes across.  TIA
