Debugging : Application defined or object defined error

Hi my code groups areas with same value i.e. it reads a cell that is not yet assigned to a area and find all cells which are connected to it ( similar to tracing the tree from its root to its leaves except that the root is the first cell that has not been assigned to any area previously) have the same value as it has to form an area.

This is the code which I have written to for the above task:

When I run the code I get the following error:

"Application defined or object defined error"

I hope someone could help me in debugging this error as excel debug is not very helpful.

Thanks in advance

When I run the code I get the following error:

"Application defined or object defined error"

Although it's helpful to describe the error, it even more helpful to also state at which line you are getting the error.

This line at the start of FindTrustZone will error if row is = 1

In the failing code (when row=1) the line tries to evaluate whether Cells(0, col) = x (trying to look at row 0 is the error)

In the second code, if row = 1, it doesn't try to evaluate Cells(row -1, col)

I don't know about using a keyword like row as a variable. Every executable line?
How do you get it to go to the other lines after it stops on the first executable row, which it should do if it causes an error?

I think you have a few logic errors.

This moves right (which I would call East), not left, and you should be checking that you're not in the rightmost column:

After correcting code as mentioned by mikerickson, I encountered a new error "Run time error 28 out of stack space". Any help on that ??

Recursive calls?
