## Re: Process Number Variable Calculations

A "\$" is needed at the end of the variable name -- not a "&". \$FFvar\$-6 should work.

## Re: Process Number Variable Calculations

What do you mean by not working? Processing fails? You do not obtain the result you expect? I am concerned that your formula could result in a negative number, which may make no sense for the calculated value.

this is in Polish "określone rzutowanie jest nieprawidłowe", it means "the specified cast is not valid"

## Re: Process Number Variable Calculations

Is the variable a standard FFCore variable (e.g., described in HELP)? Can provide me the name of the variable? Depending on variable type (e.g., string, enum, number, dimension), you may be forming a non-supported outcome with your formula. In what node are you applying the formula? Is the error posted on the job management GUI?

Unfortuneately your attached pngs are clipped. I do not understand how the formula is designated or the error message.

## Re: Process Number Variable Calculations

I see the problem. I was able to avoid the error by changing the equation order. For example - 6 + \$FFvart\$  (instead of \$FFvart\$  - 6  ) . Not a great solution but  it worked for me.

6 + \$FFvart\$ doesnt subtract, it add to the value
