Tom,

As Macer has mentioned your problem is that there is a data type mismatch somewhere. You can use the Transform function to cast all of the data types to character as in;

local superid, act
act = 'search'
superid = 'IW/NP/MR 2002/7 '

if act = 'search'
	locate for alltrim(TRANSFORM(thisform.text1.value)) = alltrim(superid)
endif


if act = 'search'
	locate for alltrim(TRANSFORM(casema.caseid)) = alltrim(superid)
endif
