I am struggling with slots, In this case I have a function int which gives either true or false. When it gives true, I want

Select[interest, (DateList[#[[1, All]]] === #)&]

to be applied however as you can see this does not work because of the slots. Problem is that I want the slot in function int[#] to be the same as the slot behind ===. How can I overcome this problem?

 If[int[#], Select[interest, DateList[#[[1, All]]]& === #], 
    2 {False}] & /@ fasteDatoer]

Simple example

Lets say that when first applied it states int[james], which is true. I then want it to Select[interest, DateList[#[[1, All]]]& === james.

@ALEXANDER This question will probably help you. – C. E. Mar 05 '14 at 13:07
Not so easy without a sample data. Please provide a minimal sample. – Kuba Mar 05 '14 at 13:07
It would b extremely helpful to provide a small toy example. As Kuba has advised you can deal with ambiguities of multiple slots by using Function[x,...]. If this does not resolve your issue an example would help. – ubpdqn Mar 05 '14 at 13:08
is it the int[#] that needs to be anonymous or is it the DateList[#[[1, All]]]&? – ALEXANDER Mar 05 '14 at 13:42
