multiple text showing after clicking CC button when slider drag
I have created a customized CC(closed captioning) in my project in storyline. functionality of closed captioning is explain below.
In the base layer there is a button. On clicking the button it will show the second Layer. In the second layer there is one video in the .wmv format and there is two CC button on same position one for video Transcript show and another for hide. There is video Transcript below the video and it is sync with video by Cue point in the Time line of the layer to sync the video. I keep multiple text boxes in the same position for Transcript. And as video progress Transcript showing. When the user clicking the CC button it is hiding the all of the Transcript text Boxes and it is hiding its self also to bring the second CC button in front. When user click second CC button it is showing the First CC button and Transcript text box of current video position. To show the only current Transcript text box do I have added a programing logic explain below.
In every Transcript text box Timeline start I am updating a variable like Trans1, Trans2, Trans3....
And when Second CC button clicked to show the Transcript. I just show the transcript as per the variable update. for example of trigger, change state of text box to normal when user click CC2 button if variable equal to Trans2. I have added this trigger for all of the text boxes to show the text box according to current video position.
It is working very fine. But I am facing a problem explain below.
in some time when user drag the slider (slider of storyline) it is showing two text Boxes in same time.
Is it happening due to slider?.
Please help me out. any suggestion can help.
Thank you in advance.
