Dear All,

I have a table with 7 columns, I created another column to the table and dragged checkbox on it. Now table as 8 columns with the first column as checkbox in each row.

I want to restrict the number of selections on the checkbox based on some value from another Limit field on the page, let's say if value in Limit field is 7 then user should be able to select maximun 7 rows and on selecting 8th checkbox it should show pop up with the message. If Limit value is 3, then the user can select upto 3 checkboxes in the table, should not allow the user to select 4th checkbox.
