Script/Global field with Numbers

[The Missing Man]

I am trying to do a simple script where I am increasing my global field + 1 for a series of looping steps but everywhere I look to add this it keeps telling me it needs to be a text field. Can I not add to a number field via a script? I know this is Filemaker 101 but any help would be appreciated.

Thanks,
