Operate Multiple Field Values

[Rodrigo_Flores]

Hi everyone. please help me with this.

I have some lookup fields, they have many values on them. I want to add a formula to multiply each of those values by a percentage (%), at the time I make this formula the total shows 1.0 instead of the multiple comma-separated values with their values reflecting the discount made by the percentage field.

Am I missing something in formulas to operate those values?

Thanks in advance

What’s the formula that’s currently generating the Subtotal field?
