[SOLVED] wise J 2.1.10 / 2.1.11 Unable to type into combo box column

I created a multi column combo box with a search facility, whereby if you deleted the text in the box you could type some characters, press enter and the contents would be searched, for matching values

With this version as soon as I delete a character in the box, the original contents are restored.

Frank has a copy of the code

Thanks for your help
