ok.. I keep getting one step forward only to find another problem!!!

I am scanning a sheet.. adding all the cell ranges together.. then I need to highlight them...

in one test
Range("A1,A2,A3,A4,A5,A6,A7,A8,A9,A10,A11,A12,A13,A14,A15,A16,A17,A18,A19,A20,A21,A22,A23,A24,A25,A2 6,A27").select
worked fine..

but when I tried:
A1,A2,A3,A4,A5,A6,A7,A8,A9,A10,A11,A12,A13,A14,A15,A16,A17,A18,A19,A20,A21,A22,A23,A24,A25,A26,A27,A 28,A29,A30,A31,A32,A33,A34,A35,A36,A37,A38,A39,A40,A41,A42,A43,A44,A45,A46,A47,A48,A49,A50,A51,A52,A 53,A54,A55,A56,A57,A58,A59,A60,A61,A62,A63,A64,A65,A66,A67,A68,A69,A70,A71,A72,A73,A74,A75,A76,A77,A 78,A79,A80,A81,A82,A83,A84,A85,A86,A87,A88,A89,A90,A91,A92,A93,A94,A95,A96,A97,A98,A99,A100,A101,A10 2,A103,A104,A105,A106,A107,A108,A109,A110,A111,A112,A113,A114,A115,A116,A117,A118,A119,A120,A121,A12 2,A123,A124,A125,A126,A127,A128,A129,A130,A131,A132,A133,A134,A135,A136,A137,A138,A139,A140,A141,A14 2,A143,A144,A145,A146,A147,A148,A149,A150,A151,A152,A153,A154,A155,A156,A157

no good...
there is a Union function that allows you to union a bunch of ranges to select them but I cant get it to work?

1) how can I select all these at once (Without converting to a range.. unless someone can figure that one out )
2) or How can I select 1 cell...but then ADD to the selection?

thanks
