I wanted to lock a column in a query and I just couldn’t be bothered making a a form. Then it occured to me I could add a blank space into the columns that I wanted locked and the user wouldn’t be able to inadvertantly change data in those columns.  You will see how it works in the following 2 samples. The user can only change the data in the last column.

Figure 1 – Adding Space locks the column from data entry

Figure 2 – Only the Rocktype field can be edited

Note: Tempvars are used to filter the data
