Storing number in field

I have a check mark on a form. Every time the check mark is checked, I would like the value in the field titled: "rawnumber" to be multiplied by 2.25 and stored in the field titled "SavedNumber". Once after the proper number is stored I want it to clear what was in the "RawNumber".

Note the field where the number is entered is an unbound field. Not sure if that matters. I am guessing I do an "After Update" event for the check mark?

if me.checkboxName=-1 then
me.savednumber=me.rawnumber * 2.25

me.rawnumber=""

end if

use the click event of the checkbox.

you can do the multiplication every click ( check or uncheck) or only if the checkbox is check.

Rey... thanks for your help on this! Trying to finish it this morning.

I used your code... there seems to be a problem with the line:

"if varnumber>=<some value> then"

It is highlighted Red when I put it in. Also, When I click the check box, it takes me to the code with that line highlighted.

Any ideas? Thanks again!

you have to replace "<some value>"  with a number, according to what you stated above

Once after the proper number is stored I want it to clear what was in the


is that a max limit or what?

Not sure I explained myself properly... when the check box is clicked. It will muliply what is in RawNumber by 2.25 and store the result in SavedNumber. Then it will erase what was entered in RawNumber.

Does that clarify?
