max and min deactivate MAX

[nsggroup]

Hi, I have the max and min feature working, however I am using several spinners on a page and it is their combined total that determines if a maximum has been found.

I have used the UP and DOWN events to capture the current total in a variable and I can check to see if this has hit a maximum.

My issue is how can I deactivate all the spinners from adding more to the total.

Basically is there an event to disable the (+) button so the user can still lower the range and this re-activates the (+) button again

thanks
