The issue is in form's combo box behaving differently in win 10 +-- win 11 with wring drop down. Open my form in win 10+ vs Win 7 you will see the odd behavior
To check later in regional settings, hope it can be fixed as many users reported this. How is result in your win 11. I presume you run my form in win 11 & things are good
The form loads with an empty combo, and if I click on it, I am presented with the three values you use to populate the combo?
Nothing untoward that I can see.
Thank you Gasman from Wales for pointing at the right direction, bullseye. Carelessly I was mislead by win 10 update to new version that removed the comma separator i set up in the previous version of win 10. Once the comma in place at Control Panel > Region, combo drop box is backed. Bravo
