Its telling me that the macro ME. does not exist.
Maybe I'm doing something wrong, I am new at this stuff.
Please include the relevant portion of any previous post, so that
other readers can have some idea of what this post is all about.
You evidently wrote the code the other replier gave you on the
AfterUpdate event line, not in the AfterUpdate code window.
Click on the Check Box field.
Display the property sheet.
On the AfterUpdate event line type
[Event Procedure]
Then click on the little button with 3 dots that will appear on that
line.
When the Code window opens, type
Me![YourCommandbuttonName].Enabled = Me![CheckBoxName] = True
'(or False, I don't rememeber which way you wanted to go with this.)
between the 2 already existing lines.
Exit the code window
Place the same code in the Form's Current event.
