Hi @kathrinfitts,
Do you want to compare the today with the date value from your sql table?
Could you please tell me post a screenshot to describe if the it is a date time value or date only value?
Actually, I suggest you compare the today date directly with the formula you set for the Label Text property if you have a date only value from sql table.
If(Today()><Formula_For_Label_Text>,Disabled,Edit)
Note that this works only when you have a date only value from your sql table.
I don't agree with @StretchFredrik that we could compare Today() with Now() because they have different data type, which one is date only value and the other one is a date time value.
If you have a date time value from sql table, you could convert the date time value into a date only value to compare with the Today()
If(Today()>DateValue(Text(First(BU).Created,"dd/mm/yyyy")),Disabled,Edit)
Note that First(BU).Created is the date time value from my data source, and I combine Text() with DateValue() to convert it into a format like "dd/mm/yyyy"
