The [math] context is very picky. It will not work correctly if the variable name includes a minus (-) or a period (.)
Example of variables that will produce failures when you try to use them inside [math][/math] are:
[math][on-hand]+1[/math]
[math][on.hand]+1[/math]
In my experience these would both produce errors. I will assume that a space will cause the same error. The underscore (_) character has no usage in any language, mathematical context or any other real world usage, and therefore it is a safe character to use in all variable and database field names.

I've gotten them to work, but not without [url]ing everything. That said, I see 2 errors in your code so try this: You have a typo of "wqSKUdatarq" instead of "eqSKUdatarq" And the variable ON_HAND needs to be stated as a variable in [] inside the [math] context. [replace db=^inventory.db&eqSKUdatarq=[SKU]]ON_HAND=[MATH][ON_HAND]+[updatevalue][/MATH ][/replace]
The wq was a typo on the email, not the actual code. I did that, but it does not update. Do you think the ON HAND, as opposed to an ON_HAND, may be the problem? ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list <WebDNA-Talk@talk.smithmicro.com>.
