Text in column A cells may contain 1 of the following: alpha, beta, gamma,
delta.

I want to search cells in column A for all of these values and, if one is
found, insert that value in the same cell of column B.

For example, cell A3 contains beta, kappa, and tau. I want to check for
alpha, beta, gamma, or delta. The search should determine that beta is
present and then place beta in cell B3.

If the search does not find alpha, beta, gamma, or delta, then "other"
should be placed in the corresponding cell of column B.

Is this possible?

Thanks,
Tom
