DAQmx Task Gives Error -200077 When Creating a Custom Scale

Primary Software: Utility Software>>Measurement & Automation Explorer
Primary Software Version: 4.3
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: Multifunction DAQ (MIO)>>M Series>>USB-6259

Problem:
I am trying to create a custom scale for the signals acquired from my USB 6259. I have created an analog input task in Measurement & Automation Explorer, and I have selected custom scale. I am using a map range scale to scale values proportionally from a range of pre-scaled values to a range of scaled values. My pre-scaled values are +/- 5V and my scaled values go from 0 to 200 volts. I have my signal input range set to +/- 5V. However, when I try to save or run the Task I am getting the following error:

Error -200077 occured at DAQ Assistant

Possible Reason(s):
Measurements: Requested value is not a supported value for this property.

How can I fix this?

Solution:
When the signal input range does not match the scaled values, as in the figure below, error -200077 can occur.

The signal input values of the device are represented with the units as the scaled values. If the scaled values are 0 and 200V, then the signal input range must also be 0 to 200V and not +/-5V. In other words, when you create a custom scale, the scaled values must match the signal input value.
