Arrays and other cells

Here's the challenge I am having. I have a SUM array formula in one cell. One of the data elements I am trying to sum up in the array cell is pulling from another cell that has a SUM formula already in it. That second cell with the formula is not an array. I am unable to successfully pull that data from the second cell to my first SUM arrany cell.

What I did was to have the value in the second cell pull to a third cell using a simple copy formula =E5 However, the SUM array on the first cell wouldn't work with this scenario either.

How can I get my SUM array to recognize either cells so that my calculation can be pulled?

Thank you

Little more detail...

Can you post the Array formula.

It should not matter to the formula how the numbers are generated in a cell it refers to... providing it is not #N/A #NAME or a String value.

If you post the formula it may be apparent what the issue is.
