I am going to write a API on progress site (ABL) but when i am going to compile it, i got the below error:

Code:

** Incompatible data types in expression or assignment. (223)
**  Could not understand line 77. (196)

Code:

and line 77 starts from here.

Assign AlertDetail.AlertId = Alert_Popups.AlertID
    AlertDetail.AlertType = Alert_Popups.Alert_Type
    AlertDetail.AlertUTCDateTime = if Alert_Client_Acknowledgement.AlertDateTime = ? then now else Alert_Client_Acknowledgement.AlertDateTime
    AlertDetail.lTimeZone = lv_timeZoneDescription
    AlertDetail.lTimeZoneoffset = lv_timeZoneOffset
    AlertDetail.PropertyId = integer(Alert_Popups.propertyid)
    AlertDetail.PropertyName = cPropertyname
    AlertDetail.Alerts_id = RECID(Alert_Popups)
    AlertDetail.AlertStatus = if Alert_Client_Acknowledgement.noack = "NoAck" then "AlertAcknowledged" else "AlertGenerated"
    AlertDetail.Comment = Alert_Client_Acknowledgement.Acking_Text
    AlertDetail.AlertAttribute = Alert_Desktop_Config_Details.Alert_attribute
    AlertDetail.AlertDisplayString = ? /* to do: Initialize as a blob */
    AlertDetail.AlertImageName = Alert_Desktop_Config_Details.Alert_Image_name
    AlertDetail.AlertPriority = Alert_Desktop_Config_Details.Alert_priority
    AlertDetail.AlertSoundName = Alert_Desktop_Config_Details.Alert_Sound_Name .

copy-lob from Alert_Desktop_Config_Details.Alert_verbiage to AlertDetail.AlertDisplayString.
copy-lob from AlertDetail.AlertDisplayString to ggDisplayString.

/* Replace variables with data */
run ReplaceVariablewithData(ggDisplayString, AlertDetail.AlertId, OUTPUT ggDisplayString).
copy-lob from ggDisplayString to AlertDetail.AlertDisplayString.

I expect the code will compile successfully in GUI procedure editor.
