Check Boxes

Hi all

Could I pick your brains.

I've add a check box widget to a page with the following variable v_TCA

I've then gone into variable and created one v_TCA with a value of 0

On page exit I've created an execute advanced action so      IF

                                                                                                 v_TCA equals 0

                                                                                            THEN

                                                                                               hide tick_a (this is a .png tick image on another slide)

                                                                                             Else

                                                                                               show tick_a

that all works fine.

On the next slide I've done the same for another task using a different variable name and button names. However this checkbox unchecks at the end of the slide (the one on the previous slide remains checked)

Any thoughts - I'm a complete beginner so if the answer is really technical I might need a walk through.

Thanks,

Matt
