Cell Validation
I am a novice any and all help will be greatly appreciated! I need to provide a list of valid usernames for cell #1, then have the user enter their password in cell #2. At this point I need to validate the entered password in cell #2 against the another sheet containing the valid usernames and passwords. If the password is correct they may continue on, if the password is invalid they must re-enter the password until it is valid.
I have been able to setup the List drop down box for the username, but I am able to continue if I enter nothing, I need to have a name entered from the list. Also I need to then have the user enter their password into cell #2 and then using the username and password from cell #1 and cell #2 verify the username and and password from another sheet using data from column a (username) and coulmn b (password). How can I accomplish this? Thanks JLW SR |

Worksheet: UsernamePW A1:An -- list of valid User Names with no blanks B1:Bn -- list of corresponding passwords (you probably will want to hide this sheet) Define a name (to get around problem of Data Validation referring to another sheet: Names refers to: =OFFSET(UsernamePW!$A$1,0,0,COUNTA(UsernamePW!$A:$ A)) Note that Names is a dynamic range, and you can add names to the list and the Names range will change accordingly. On your Entry sheet, select A2 Data Validation List Source: =Names set the input message and error alert messages however you wish Select B2 Data Validation Custom Formula: =$B$2=VLOOKUP($A$2,OFFSET(Names,0,0,,2),2,FALSE) Again, set the input and error alert messages to suit you. |
