update field

Isn't multiplying by 1.2 going to increase the price by 20%? Your bank
account will love it. But it might be a little bit of a shock to your
customers :-)
I suggest trying

DoCmd.RunSQL "UPDATE Products SET SalesPrice = SalesPrice * 1.02"

Use an update query like
UPDATE Products SET Products .SalesPrice = [SalesPrice]*1.02;

Make sure you multiply by 1.02. The 1.2 you suggest is a 20% uplift. The
chancellor would not like it

WHERE clauses are used to select the records, not update the value. The SET
clause is used to update the value.

Here's some SQL from a Query created using the QueryBuilder that works on a
table in one of my test databases:

UPDATE tblSomeNums SET tblSomeNums.AFloat = [AFloat]*1.5;
