Origin Ver. and Service Release (Select Help-->About Origin): Origin Pro 7.0
Operating System:Windows XP sp3

Hi, I fit the data by the user-defined function as,
y=25000*b*(a+x)-((50000*b*a+50000*b*x)^2-4*b*x)^0.5.

Error code came out when i tried to compile the code.

Error, invalid term
Error, general compile error
Error, error(s) found in compiling function _nlsfFittingFunction
Error, invalid term
Error, general compile error
Error, error(s) found in compiling function _nlsfFittingFunction

When I use it to fit, errors accorder.

Attention!
Error,28037. Likely caused by errors in user-defined formula or poor parameter initialization.

Would like to help me to conquer them?
