Label caption changes on textbox entry

At some point in writing/rewriting code for a label and related textbox I've created an error. The label has a caption name "Part" and the textbox is named "tbxPart". On the form, when a value is entered in the textbox and tabbed off, the label caption changes to "-2147483630". There is code that changes the label text to red and the textbox back color to salmon if left blank when the user clicks the Add button.

All was working as planned and then while making some changes (don't know exactly when/what) this started happening.

Any Ideas?

You'll need to post the code so we can troubleshoot please

Hopefully this works, I've attached a .txt file with the complete code for the form.

Norie,

That does fix the issue. Now I need to go look at some of the other forms and see what I have different there that allows this to work. Must be some tiny difference in the setup.

Thank You!!
