i have cvl as variable in my report,

[pre] IIF(dtrupcode="VL",1,0) [/pre]

it works fine if i put a text box and write in expression "cvl".

if i want to only print the cvl when cvl>0 i do,

[pre]

IIF(cvl>0,cvl,0)

[/pre]

but say cvl=4, i want it to display "VL: 4" so i do it like this,

[code]

IIF(cvl>0,"VL: "+trim(str(cvl)),0)

[/code]

it only prints "4".

what's wrong, any help pls?
