If you don't mind the unique ids being related, just append a string to the end of the [cart] value. The problem is that, as you have discovered, the [cart] generates a string of digits too large to represent as a number except with scientific notation. NOTE: you should not just use [random] to create your unique portion of the id, since technically speaking [random] numbers could include a finite sequence of the same number. If you have a fixed number of unique ids which you need to create, you could try something like this: [text show=f]id1=[cart]-1[/text] [text show=f]id2=[cart]-2[/text] [text show=f]id3=[cart]-3[/text] [text show=f]id4=[cart]-4[/text] ... (you should use some sort of delimiter between the [cart] and the sequence, so there is some visual clue that something is going on). In fact, you could have a [math] value which you use as a sequence number and increment after every new id based on the [cart]. But the important thing to note is that the id must be a text variable, not a math variable.
