1. The ri!newRIP_cdt.clinSubtotal value is captured in the preceding script task. 
2. ri!newRIP_cdt.totalEstimate = ri!newRIP_cdt.handlingCost + ri!newRIP_cdt.freightCost + ri!newRIP_cdt.clinSubtotal
3. ri!newRIP_cdt.handlingCost is calculated using the ri!newRIP_cdt.handlingRate * ri!newRIP_cdt.clinSubtotal OR the user can overwrite the handling cost value.
Issues: 
1. If I enter a handling rate, the handling cost is properly calculated and ri!newRIP_cdt.totalEstimate value updates.
2. If I overwrite the handling cost value, the ri!newRIP_cdt.totalEstimate value does not update.
3. When I enter a freightCost, the ri!newRIP_cdt.totalEstimate value does not update.
