This does not solve my problem.
I would like to clarify the problem more clearly:
I enter 1 in cell 1 and 2 in cell a2 , while 0 in b1 and 1 in cell b2.
Now I want to merge both the columns (a,b) and and get the result in column c1 as 1 and 2/1 in cell c2.
Please provide a suitable formula to help me get rid of the problem.
