trying to activate a button in iwp

[alphanitrate]

I apologize if this is not the right place but I have users accesing my DB via IWP - unfortunately the enter/return key does not function the same way for them as it does for me.

Here's what I need help with - I have a field that only accepts a 7 digit SKU - when they hit enter it creates a new line.

Is it possible to set up a calculation for that field so that when it has 7 digits entered- it could trigger the script that my button currently does?

I would only need it to work in "Find mode"
