Evaluating return value of script

[ChrisF]

Using VBPro v7.2

I have a Run Script step, which has a VBScript. The VBScript runs a function in a Access DB, and the Access DB function returns a -1 on fail, an 0 on pass. How can I make my Run Script step use the return value of my Access DB function, so I can evaluate a pass/fail condition on the Run Script step? Thanks!
