So i found a Code that works for number then Letter, I tried to modify is so the user entering data in the cell need to be ex:"52TSQ1234512345". I got it to the point where they have to enter ex: "12PQS" (numbers and letters are examples, it can be any number and and letter(in CAPS). This is what i got so far but something is off, and i can’t seem to find the solution anywhere.
"=AND(LEN(A1)=15,ISNUMBER(VALUE(LEFT(A1,2))),CODE(MID(LOWER(A1),3))>=97,CODE(MID(LOWER(A1),3))<=122)),ISNUMBER(VALUE(RIGHT(A1,10)))"
try this
=AND(LEN(A1)=15,ISNUMBER(VALUE(LEFT(A1,2))),CODE(MID(LOWER(A1),3,3))>=97,CODE(MID(LOWER(A1),3,3))<=122,ISNUMBER(VALUE(RIGHT(A1,10)))Two issues
Midformula had a missing argument()positions, in particular the two at the end ofCODE(MID(LOWER(A1),3))<=122))
