Cannot Locate Field

Hello,

R6 dev.

I’ve created one mask (with automatic refresh field option checked)

In this mask I’ve build un list of dialog field (named toto) with a computed formula

I’ve another list of dialog (named plouf) who appear when I check a value from the first field (toto).

The hidden/show work perfectly, but when I put the cursor of my mouse in the second field (plouf), Lotus say (Error : Cannot Locate Field)

Anybody have an idea ?
