Hello everyone, What I am trying to do is create a hash to test some code I wrote. The problem is I have little experiance with hashes so I went on line and searched the web and put together my best guess. The Hash call I need to meet is as follows: 
@idlarge = ($Data_Hash{$Call_Hash{"TST_" . "IDS_Large_1"}}, $Data_Hash
+{$Call_Hash{"TST_" . "IDS_Large_2"}}, ...

@idsmall = ($Data_Hash{$Call_Hash{"TST_" . "IDS_Small_1"}}, $Data_Hash
+{$Call_Hash{"TST_" . "IDS_Small_2"}}, ...

@Vg = ($Call_Hash{"OPT_" . "VGS_1"}, $Call_Hash{"OPT_" . "VGS_2"}, ...

What I am doing is creating the hash to these calls. After searching online I put it all together and came up with the following: 
%Data_Hash = (
    %Call_Hash = (
            TST_IDS_Large_1 =>2.9E-12,
            TST_IDS_Large_2 =>1.85E-12,

            TST_IDS_Small_1 =>1.86E-9,
            TST_IDS_Small_2 =>2.83E-9,
        ),
    OPT_VGS_1 =>0,
    OPT_VGS_2 =>0.02,
    
);

From trying to call the hash I can tell you that what I have is not correct. I can get the information in the first level of the hash but nothing beneith it. Can someone please tell me where I have gone wrong in creating the hash? Aaron
