hello.

new to forums, usually try to figure it out myself but i cant seem to get the right formula this time. i have tried Vlookup, Hlookup, Match, Index but nothing works correctly.

sheet 1
column a = 1st names
column b = diff letters of the alphabet not in any particular order & can be duplicates
column c = i want this to be the # of the letter ie: a = 1, b = 2, c = 3 etc... so when i put 'N' in column b25, column c25 shows me 14 or put 'D' in column b9, column c9 shows me 4

so on sheet 2 i made a table & i called it 'abc123table'
column a: row 1 = a, row 2 = 1
column b: row 1 = b, row 2 = 2
column c: row 1 = c, row 2 = 3
all the way to column z: row 1 = z, row 2 = 26

any help would be appreciated. thanks in advance.
