Dynamically create array and display data graphically

Hi,
Please bear with me if you find this a simplistic problem. Just learning to find my way around mathematica.
b = Import["C:\Practice\example1.xls",{"Data",1}] (* Import file - several columns of data with first row having headers *)
Manipulate[Manipulate[DateListPLot[{Take[b,{2,p}][[All,a]]}, {{2009,7,8},Automatic,"Day"},Joined->True],{p,2,35,1}],{a,2,5,1}]
In this code, I am able to specify the column I want displayed using the outer manipulate fn, and the inner manipulate function changes the number of rows of data displayed.
Now I want to change this function so that the outer manipulate fn specifies the "number of columns" to be displayed. So that if a = 3, I see three series in the graph with "p" rows of data shown in the graph.
I tried the following with no success:
Manipulate[{Do[col[[x]]= DateListPLot[{Take[b,{2,35}][[All,x]]}, {{2009,7,8},Automatic,"Day"},Joined->True, DisplayFunction->Identity],{x,2,a,1}],
Do[Show[col[[x]], DisplayFunction->$DisplayFunction],{x,2,a,1}]}, ,{a,2,5,1}]
Was basically trying to loop "a" times to dynamically create an array of dimension [a, 35] and then display them all together using Show function. But value of "a" doesn't get passed on and I believe use of the Do loop is also wrong here.
Thanks for ur help.
Regards,
Tuhina
