How do you pass 2 parameters in cfgridcolumn href?

Brichsoft - Thanks - I need some further guidance (novice)
in the query i get "keyword not found where expected"
none of these syntax's work, talking to oracle db:
MRE_PRIORITY_FY.TDA_UIC & '~' + MRE_PRIORITY_FY.ACN As LinkColumn,
(MRE_PRIORITY_FY.TDA_UIC) & '~' + (MRE_PRIORITY_FY.ACN) As LinkColumn,
((MRE_PRIORITY_FY.TDA_UIC) & '~' + (MRE_PRIORITY_FY.ACN)) As LinkColumn,
((MRE_PRIORITY_FY.TDA_UIC) and '~' + (MRE_PRIORITY_FY.ACN)) As LinkColumn,

:) I tried that as well. "invalid number ", both the fields are "CHAR"s

I'll check the second option - thanks

Excellent - it works!  Almost there.
It passes the values toretrieve file with "Variable GRIDKEY is undefined." error - see http:
MRE_ReqDetailOverviewgood_Update.cfm?CFGRIDKEY=012009001~MCW07CAA00
I did as you suggested above:
<CFSET ACN = GetToken(GRIDKEY,1,"~")>
<CFSET TDA_UIC = GetToken(GRIDKEY,2,"~")>

Then in sql I did which does not seem correct:
WHERE MRE_REQUIREMENT.ACN ='#URL.GRIDKEY#'and MRE_REQUIREMENT.TDA_UIC = '#URL.GRIDKEY#'

Thanks for your help, this is huge for me...

:) Ok GRIDKEY needs to be CFGRIDKEY

Now, how does it distinguish the difference between CFGRIDKEY1 for ACN and CFGRIDKEY1 for TDA_UIC?

WHERE MRE_REQUIREMENT.ACN ='#URL.CFGRIDKEY#'and MRE_REQUIREMENT.TDA_UIC = '#URL.CFGRIDKEY#'

Brichsoft, actually I just got this working because they're declare in the CFSET above...

WHERE MRE_REQUIREMENT.ACN ='#ACN#'and MRE_REQUIREMENT.TDA_UIC = '#TDA_UIC#'

Good job - thanks for your help
