Identify presence of difference texts across DIFFERENT cells, per group

[Corp_exceller]

I have the below data and want to see how I can achieve the last column.

Basically wanting to check for text down a column and per code so for example, I'm not looking for cells that contain "A" and "B" in the one cell, I'm looking for "A" and "B" across cells i.e. groups of codes, so that I can identify whether e.g. Code 1 has gone from A to B (presence of A and B in levels), or whether it's just stayed at A (presence of just A in levels), or whether the code has skipped level A and gone to B (presence of only Bs in level).

Apologies if I've been unclear.

Code	Level	Progression
1	A	A TO B
1	A	A TO B
1	A	A TO B
1	A	A TO B
1	B	A TO B
2	B	B ONLY
2	B	B ONLY
3	A	A ONLY
4	A	A TO B
4	B	A TO B
4	B	A TO B
5	A	A ONLY
5	A	A ONLY

Remember that for any formula, you can see the calculation steps by selecting the formula cell and then using the 'Evaluate Formula' button in the 'Formula Auditing' section of the 'Formulas' ribbon tab.

That is a useful tool when trying to understand how a formula works. Reducing the formula range sizes can help with viewing that window to follow the calculation steps.

Useful but very hard to see.
