Apply changes to all textbox instead of selecting individual

Want to change all text boxes together. if Do individual then positive result but when tried to do as group its fails.

This is not the Iverson Language APL, where operators understand arrays.

You need a FOR EACH loop over that list of TextBoxes, and to call the procedure inside the loop, one box at a time.

BTW, rename your procedures immediately to avoid a bug in the Blocks Editor.

"One box at a time." have to apply 28 boxes Wanted group application. if you can suggest then other any extension!

in the procedure, you need a for each item block to set each textbox

or like this:

perfect. Its resolve... thanks a lot
