It is possible.
But what exactly do you mean by "get that away"?
You could prevent the user from entering a minimum larger than in store.
You could show an error message when it happens.
You could replace the negative with zero
You could hide or delete the record.
To list just a few possibilities
i just want it to make it invisible thanks for the answer philModjunk
If you are using FileMaker 13 or newer, you can select a field while in layout mode and use Hide Object When to make the field disappear when the value of the field is less than zero.
Or do you want to remove a Product from a value list when its current inventory on hand is 0 or less to avoid the negative result in the first place?
Thanks for your idea , i think i try this one , i let you know if this is the trick where i was looking for.
sorry that it took a while ! your advise worked out very well
