Help on Match formula to pair a data within the same column

[blackorchids2002]

Hi Masters,

I badly need help on how to use match to pair data within the same column. I would need a formula to pair the data. Below is the table to explain further.

I have columns A to G. I want to pair the weight in column B, then column C and so on and so forth.
For you to pair the data, let say in column F, I could pair 2.100 to 2.130 or I could also pair 2.100 to 1.800. I want to come up in paring within the range of +0.030 and -0.030.

Another example on the same column F, I can pair 2.115 and 2.130. I cannot pair 2.115 and 2.170 because it is not within the weight interval of +-0.030.

I needed help on how to formulate the formula.

	A	B	C	D	E	F	G
	Weight	1.700	1.800	1.900	2.000	2.100	2.230
1	1.710	1.710	-	-	-	-	-
2	1.700	1.700	-	-	-	-	-
3	1.680	-	-	-	-	-	-
4	2.040	-	-	-	2.040	-	-
5	2.170	-	-	-	-	2.170	-
6	2.115	-	-	-	-	2.115	-
7	2.130	-	-	-	-	2.130	-
8	1.840	-	1.840	-	-	-	-
9	2.240	-	-	-	-	-	2.240
10	2.100	-	-	-	-	2.100	-
11	2.140	-	-	-	-	2.140	-
12	2.000	-	-	-	2.000	-	-
13	1.800	-	1.800	-	-	-	-
14	2.100	-	-	-	-	2.100	-
15	2.245	-	-	-	-	-	2.245
16	2.115	-	-	-	-	2.115	-
17	2.130	-	-	-	-	2.130	-
18	1.825	-	1.825	-	-	-	-
19	2.225	-	-	-	-	2.225	-
20	2.160	-	-	-	-	2.160	-

								I wrote a small macro to check every possible pair and list all that meet the criteria (had to change - to 0)

<colgroup><col width="64" span="9" style="width:48pt"> </colgroup><tbody>
