Custom Workflows created for Office 365 Sharepoint is not changing the stages .Workflow is getting completed Without going to next stage

Hi ,

I am running a Workflow on our online share point of office 365 in share point designer . I Created a Workflow with 4 stages on a current item value  with one column  consists of 4 fields so that based on the field selection in the Column file will change the stages .

Now I kept a condition in stage 2 like , If user will select one field ,file will go to stage 4 or else if they select another option  go to stage 3 .

Transition to stage :

If Current Item:Report Status equals Send back to Writer

    Go to Stage 3

Else

    Go to Stage 4

Now I am facing a problem , When user selects any field in the column , file is not going to any stage (neither stage3 nor Stage 4) .Even though they selected the option which given in the condition file is not moving to another stage , the workflow is getting completed .Please help me out on this
