Locking/ Unlocking specific cells based on value

[ChelseaRanee]

HI!

I've tried reading through different threads and sites trying to find something code that will work for me but I don't know enough (or anything) about VBA to modify them to work for what I need so I'm hoping someone can help me out.

I have a spreadsheet set up for work that will be edited by each store (1 copy each, not shared). They will be entering test results in but the super important part is that they enter the date first so that it doesn't affect other formulas.

I'm wanting to set up an auto lock/unlock for when the date is entered so that they cannot possibly enter things in the wrong order.

Info:
Cell B9 is where the date will go and will always be unlocked.
Cells C12:E12, C17:E17, C22:E22, C27:E27, C32:E32, I12:J12, I17:J17, I22:J22, I27:J27, and I32:J32 will need to unlock once the date is entered (any value for unlock key would be fine if that's easier)
The rest of the worksheet will always be locked if this is possible.
Sheet name where this will be active is named "Data"

Thanks in advance!

Could you use data validation =$B$9>0 (No tick in the ignore blank box)
