>On a form, I have opened the free table and want to be able to click the checkbox and the value for the tied variable to change.

Is this supposed to be "Variable" or a "Field" in your free table? Either way, simply set teh ControlSource of the checkbox to the variable, field, or form property you wish to synchronize with the value of the checkbox.

>If the check is removed then the tied variable is changed and two other variables are changed as well. The two additional variables are logical variables. Basically renove the check turns off the other two. The other two variables are not on the same form. When I try to change them using '=' or 'store' I get an object .... not found error message. Does anyone have any ideas?

You need to find a way to make these variables avialable. Can you desribe a little more about how the variables are all laid out and the purpose of this form? Then we'll know what to do.
