Hi all

have read the FAQ for attributes and looked up the forums here, but can't work out why this is happening.

What I'm looking to do is have a base price factor increase depending on attributes. I have a test option name with a dropdown list of option values attributed to it, and I've associated the option with the product I want. That all seems to work fine.

However, when I try to increase the price on any of my option values using price factor (for example if I enter "1.2" in price factor and then "insert", I get the above error.

What am I doing wrong?

TIA for any help
