Creating TimeSpan
Any one got any idea how I can create this variable

<cfset CachePeriod = CreateTimeSpan(CacheQuery.property)>

I always get the error: " The function takes 4 parameters."

Cheers

it's as follows

CreateTimeSpan(days, hours, minutes, seconds)

so it will be something like
CreateTimeSpan(0, 0, 0, CacheQuery.property)

hope it helps

createTimeSpan takes four arguments. You could try creating a string and feeding that into the function call:

<cfset theTimeSpan = "0,0,20,0" />
<cfset CachePeriod = CreateTimeSpan( theTimeSpan )>

Cheers Kiteless: I had actually tried that before, though. It threw the same error.

I gave up and found another method - but for future reference: there's now way to tell CF to resolve a variable before another, is there?

Cheers

I would just set the variable equal to the actual timespan that createTimeSpan returns, like this:

<cfset theTimeSpan = createTimeSpan( '0,0,20,0' ) />

<cfquery cachedWithin="#theTimeSpan#"...>
