Formula for multiplying a fixed value by any random number

Hi, do to the nature if how the generator works, certain fields can’t be inputted by me as the would affect how my SQL table works. I’m trying to get a cost value (65) to be multiplied by a random number between 1 and 500. What would be the formula for this? 65 * RandInt(499)+1 was the closest i could think of.

For context it’s the base price for seeing a consultant, 65 euro * by the amount of times a patient visited said consultant , any time between 1 and 500. I can’t input a “number of times visited” field type as that already occurs in another table for my SQL and there’s no referencing feature in the generator.

Try 65 * (random(1,500))
