USA Form 1116

[YKi]

Hi I have a question on On line 5 of the Form1116, Foreign Tax Credit. I file 1040 btw.
If let say, I only have rental income of $5000 and a foreign Capital loss of $4000. Do I report $3000 on line 5 or $4000 on line 5?

I am aware that the US capital loss is cap at $3000, but does this affect line 5 on form1116?
Moreover, I have read pub514 and the instruction for line1114, also have completed the worksheet A mentioned in the instruction, but I am still confused on the amount input on line 5.

Any help would be greatly appreciated.

Thanks
