As you can see below from the file delay.h "x must not exceed 255". Your parameter
driveValue is an int.

/*
 * Delay functions for HI-TECH C on the PIC
 *
 * Functions available:
 *  DelayUs(x) Delay specified number of microseconds
 *  DelayMs(x) Delay specified number of milliseconds
 *
 * Note that there are range limits: x must not exceed 255 - for xtal
 * frequencies > 12MHz the range for DelayUs is even smaller.
 * To use DelayUs it is only necessary to include this file; to use
 * DelayMs you must include delay.c in your project.
 *

Could that be it ?
