Inserting parameters into Manufacturing View

[hacdunqh]

I'm trying to automate machining process, beginning with all axial operations. Problem is trying to set speeds and feeds based on the material assigned to CatPart. I've inserted user parameters within manufacturing view using Parameter Explorer command icon. I'm trying to create a formula linking one of these parameters to `Spot Drilling.1\MfgParameter.2\MfgFeedrateParameter.3\Machining feedrate` and the other user parameter to `Spot Drilling.1\MfgParameter.2\MfgSpindleParameter.1\Machining spindle`. I've also written a rule that has no syntax errors. Looks good. Problem is when I apply catalog with this process, speeds and feeds do not change as they should. Problem appears that user parameter shows IPM=1in_mn=`Spot Drilling.1\MfgParameter.2\MfgFeedrateParameter.3\Machining feedrate`. Much the same for the RPM parameter. How can I make IPM=`Spot Drilling.1\MfgParameter.2\MfgFeedrateParameter.3\Machining feedrate` and get the 1in_mn out of there.
