Hi,

I have the following script within a repeat loop:

IF `ng_r_nz GE 1` THEN ;\

let wk_new=IF sie_wk THEN sie_wk ELSE (`nz_spvl`) ;\

ELIF `ng_r_zo GE 1` TEHN ;\

let wk_new=IF sie_wk THEN sie_wk ELSE (`zo_spvl`) ;\

ELSE ;\

let wk_new=IF sie_wk THEN sie_wk ELSE (`ms_spvl`) ;\
ENDIF ;\

I would like to set the missing data value to
-> nz_spvl if ng_r_nz >= 1
-> zo_spvl if ng_r_nz <1 but ng_r_zo >= 1
**ERROR: command syntax: Entire ELIF statement should be "ELIF expr THEN"

ELIF 0 TEHN

What did I do wrong?

The following link: ../../documentation/users-guide/commands-reference/IF
provides the following example:
